The solar market in India has grown beyond the utility scale solar farms. Solar water heaters, solar pumps, maintenance services, solar products, energy services and rooftop solar are all opening up opportunities for both small and large enterprises.
This is important to an entrepreneur as it shows that a solar business does not always require a large scale solar power plant or a factory. Certain businesses can start with technical know-how, a few pieces of equipment, supplier relations and effective local sales.
As of July 31, 2026, the total installed solar capacity in India is 164.59 GW with approximately 30.74 GW of grid connected rooftop solar. Beyond the installed solar there are also opportunities for installation, cleaning, inspection, monitoring, maintenance, spare parts and other solar related services.
Meanwhile, there are initiatives by the government promoting residential solar. The central government has approved ₹75,021 crore for PM Surya Ghar: Muft Bijli Yojana for the installation of rooftop solar to one crore households. This scheme offers central funding for rooftop solar in residential buildings for those projects that comply with the existing scheme.
This guide presents practical Solar Business Ideas that can be pursued with relatively little investment. For each idea, there is information regarding customer base, risk involved, growth opportunity and skills required. Using this information, a business idea can be selected that is appropriate to the individual and not just the idea that promises the highest return.
Why is Solar a Business Opportunity in India?
Solar is not only used for utility scale power generation anymore. Solar can be used in various forms across homes, shops, factories, schools, farms, housing societies, offices and other buildings.
A homeowner can use solar on the rooftop to decrease their electricity bill. A farmer can benefit from a solar irrigation pump. A factory may require a larger rooftop solar installation. A housing society can benefit from solar installation in common areas. An already existing solar customer can require maintenance or cleaning of solar panels.
Each of these customers presents a unique business opportunity.
Rooftop solar growth provides great opportunity for small businesses. Residential customers can apply via the National Portal under PM Surya Ghar and pick a solar service provider to install solar on their rooftops. The announced subsidy for PM Surya Ghar states ₹30,000 per kW for the first 2 kW and ₹18,000 per kW for every kW beyond 2 kW up to a maximum of 3 kW. The total residential CFA under the scheme is set at ₹78,000.
However, this opportunity does not imply a guarantee of profit. The solar industry is highly competitive. The end result can be influenced by such factors as quality of solar equipment, installation, sales, supplier pricing, working capital, warranty management, and the local electric utility.
What Is a Low-Investment Solar Business?
A low-investment solar business is not one that necessarily requires very little investment. Rather, it is a business that can be started with little investment in solar equipment, expensive manufacturing facilities, large warehouses, or expensive equipment.
A service business can often require significantly less investment than a business that relies heavily on inventory.
Someone with an understanding of electricity could start with a business providing solar system inspections and maintenance. Someone with strong sales ability could start as a reseller of solar products or a lead generator for solar products.
The investment required will differ depending on location, business type, equipment, transport, staffing, registration and whether or not you sell inventory. Thus, the information below should be used as planning references and not as assured costs or profits.
11 Solar Business Ideas With Low Investment
1. Solar Panel Cleaning Business
Cleaning solar panels is one of the easiest service businesses within the solar industry.
Solar panels can become coated with debris such as bird droppings, pollution, and dust. As such, solar panel owners may require periodic visual inspection and cleaning. The cleaning can be done manually on rooftops or with more specialized equipment used for larger solar installations.
A small business can begin with cleaning equipment, safety gear, transportation, basic training, and delivery to local solar customers.
Potential customers can be schools, factories, offices, shops, homes and operators of solar facilities.
The main benefit is that you are offering a service rather than a large physical product. You can also provide package options for regular cleaning rather than only ad-hoc cleaning services.
Safety on rooftops does pose a problem. Adequate training, fall protection, electrical safety, and insurance (or other safety measures) appropriate to the type of work should be provided.
- Best for: Those new to business who like the service type of business and who would like to begin locally.
- Investment level: Low
- Path to growth: Cleaning → inspection → maintenance → AMC contracts
2. Solar AMC and Maintenance Services
AMC stands for Annual Maintenance Contract. Rather than providing a service to a customer and charging them once, these contracts provide for agreed levels of maintenance over a specified period of time.
A solar AMC may consist of periodic cleaning, inspection, basic solar system checks, inverter checks, cable and mounting inspections, coordination of repair work, and periodic inspection. The services provided should be specified within the contract.
The value of this type of service increases with the number of solar systems installed in a given area. The most recent capacity data from MNRE indicates a large and expanding installed base of solar systems in India, including rooftop systems.
A company that maintains or installs 50 roof-top solar systems can provide annual service packages instead of waiting for a client to call in when trouble arises. This can improve revenue predictability.
This type of company does not have to manufacture solar systems. However, the company would need technical skills, equipment, transportation, trained employees and a system for tracking service performed.
- Best for: Electricians, technicians, solar installers and entrepreneurs with the ability to assemble a technical workforce.
- Investment level: Low to medium
- Path to growth: Residential AMC → commercial AMC → larger solar O&M contracts
3. Solar Consultancy
Not all solar clients know exactly what type of system they need.
A consultant can provide a customer with knowledge regarding their electricity use, the amount of space available on the roof, the potential size of a solar system, types of equipment that can be used, some basic cost information, installation considerations and how to interact with an installer.
A consultant does not need to have a large inventory of solar products in their warehouse.
Consider the small business owner who has received three quotes for solar on the roof but does not understand the difference in system size, panels, inverters and costs. A consultant can assist in comparing these quotes and can help a customer identify the questions they should be asking.
A consultant can charge for site assessment, feasibility, proposal analysis, energy analysis, project coordination or any other service that is clearly defined.
However it is important not to appear to be an expert in a field unless you actually have the experience and qualifications.
- Best for: Technically experienced entrepreneurs, experienced salespeople, energy professionals and engineers.
- Investment level: Very low to low
- Growth path: Consultancy → project coordination → installation partnerships → EPC.
4. Reselling of Solar Products
It is possible to sell solar products without having to manufacture them.
Products could include solar fans, solar chargers, small solar systems, solar lights, lanterns, batteries, inverters and all other accessories. The products sold should be based around what is available locally and what suppliers can provide.
A solar products reseller can sell through an office, small shop, online, social media or a combination of these.
Do not over-order without knowing your market.
Instead of ordering 100 different solar products, begin with ten or five products that address specific needs of your target customers. Then determine which products sell and gradually increase the number of products.
Margin will differ from product to product, brand to brand, volume to volume, supplier to supplier, warranty to warranty and from competition to competition. Labeled margins should not be assumed as assured profit.
- Best for: Retailers, distributors, sales people and local contacts with entrepreneurial spirit.
- Investment level: Low to medium.
5. Trading in Solar Spare Parts and Accessories
Solar is more than just panels.
Cables, connectors, mounting hardware, protection devices, switches, fasteners, tools, monitoring systems and other accessories are used by installers and service technicians.
This could offer scope for a B2B business.
Rather than selling complete solar solutions to domestic consumers, provide frequently required items to local installers and maintenance businesses.
The benefit of this is that repeat B2B customers can order more frequently than private individuals. The issue is stock management. Over stockpiling of slow-moving items ties up cash.
Begin with products that have relatively predictable local demand. Also establish relationships with a number of suppliers, rather than just one.
- Best for: Electricians, B2B sales people, traders and hardware suppliers.
- Investment level: Low to medium.
6. Solar Installation Services
Solar installation can be a great business opportunity for individuals with technical or electrical skills.
For small and residential buildings, rooftop can be a source of focus. For major equipment, orders can be placed based on confirmed orders and there is less issue with large storage capacity.
Scope of work can vary from site survey, installation of systems, mounting, wiring, equipment installation, testing to coordination with electricity authorities or DISCOM procedures depending on the project.
Compliance is important. For government sponsored rooftop programmes, there may be registration requirements for vendors as well as technical and procedural specifications. MNRE has issued a registration process for vendors participating in PM Surya Ghar. Entrepreneurs should refer to the current scheme and registration process on the MNRE website before bidding on such projects.
Selection of equipment is also important. For some government, government assisted, net metering and other projects there are eligibility criteria defined in the ALMM rules issued by MNRE. Entrepreneurs should refer to the latest ALMM list applicable to the project before sourcing equipment for such projects.
- Best for: Technicians, engineers, electricians and entrepreneurs who want to create technical skills.
- Investment level: Medium.
7. Solar Lead Generation and Digital Marketing
A missed opportunity in the solar space.
Solar businesses require customers. However many installers are technically proficient but poor at marketing. With digital marketing skills you can help generate qualified leads via social media, local listings, content marketing, landing pages, WhatsApp marketing, search engines and more.
Solar panels do not need to be bought.
For instance a digital marketer could set up a website targeting enquiries about rooftop solar in one city, generate leads and then work with verified solar installers under a clear business arrangement.
Quality of leads is what matters. Just because you send random phone numbers to a solar installer doesn’t equate to producing qualified leads.
Specialization can be in one of the following areas:
- Residential Rooftop Solar
- Commercial Rooftop Solar
- Solar Pumps
- Solar Water Heaters
- Solar Maintenance
- Solar Products
- Best for: Agencies, website owners, salespeople and digital marketers
- Investment level: Very low
- Path to growth: Lead generation → marketing agency → local solar market place → comprehensive solar marketing company
8. Solar Dealership or Distribution
Entering into a dealership arrangement can provide you with existing products and existing suppliers. However, it tends to require more working capital than a consultancy or installation business.
Products a dealer can sell include solar thermal systems, solar collectors, solar pumps, solar lighting, batteries, inverters and complete solar systems, depending on the arrangement.
Simply being a dealer does not automatically give you customers.
Successful dealer operations require a local market, sales capability, after sales service, supplier support, and effective inventory management.
Prior to entering into an arrangement, ensure that you have clarity on the minimum order quantity, territory provisions, warranty procedure, credit terms, return policy, marketing assistance and the suitability of the product to the projects you will be servicing.
- Best for: Distributors, sales professionals, existing retailers and entrepreneurs with local contacts.
- Investment level: Medium.
9. Solar Water Heater Sales and Service
Solar business is not only on solar PV panels.
There is also a well established use of solar in solar water heating. According to MNRE solar water heaters are a form of solar thermal system which can be used for domestic and non-domestic purposes including hospitals, restaurants, guest houses, canteens, hotels and hotels.
A business can provide installation, maintenance, repair and/or selling of solar water heating systems.
This would be suitable for buildings which have a regular demand for hot water such as hospitals, hostels, hotels, residential buildings and other similar premises.
Before entering this market it is important to understand the difference between solar PV and solar thermal systems as the products, standards, customer requirements and installation differ between the two systems.
- Best for: Plumbers, technicians, building-service contractors and local distributors.
- Investment level: Low to medium.
10. Solar Pump Sales and Service
Solar has another application in agriculture.
Solarisation of agricultural pumps is supported by the PM-KUSUM scheme and standalone solar agricultural pumps have been incorporated into one of the components of the scheme. Also, information such as vendor lists and service centre details are available on the national portal.
A small business can get involved in this market by offering sales, installation assistance, maintenance, repair or local service. The opportunities available will depend on the state level implementation and eligibility.
More technical knowledge is required for this business beyond the sale of small solar products. Factors such as water needs, pumping requirements, site requirements, electrical systems, and rules associated with the government scheme need to be understood.
Not all farmers are eligible for subsidy. Subsidy schemes are implemented and eligibility is governed by existing state and government policies.
- Best for: Rural entrepreneurs, solar equipment dealers, electricians and technical solar service providers.
- Investment level: Medium.
11. Solar Training and Skill Development
The solar industry is expanding and requires trained individuals to install, operate, maintain and repair solar energy systems.
MNRE has announced a Human Resource Development programme for the period 2026-27 to 2030-31 that will provide short term training and skill development in the area of renewable energy.
This opens up opportunities for trained individuals and training providers.
A small training enterprise could provide training in basic solar PV, solar installation, electrical safety, solar system maintenance, solar sales or solar entrepreneurship.
But, training must be conducted with real skills. Only confer certification that suggests government endorsement if you actually possess that power.
- Best for: Engineers, solar professionals, trainers and solar training businesses with experience.
- Investment level: Low to medium.
How to Start a Solar Business Step by Step
You don’t have to start small; you just can’t start without a plan.
Step 1: Choose one customer group
Don’t start out by saying, “I sell all things solar.”
Choose a customer segment.
For example: “I offer rooftop solar maintenance to residential customers in my city.”
That statement is easier to market than a company selling to all.
Step 2: Study local demand
Talk to both current installers and prospective customers.
What do you find?
- What products are in demand?
- What problems are being complained about?
- What services are lacking?
- How many companies currently provide these services in your area?
- What areas lack service?
- What are current prices for these services?
These questions will help you avoid putting money into a product with little or no demand.
Step 3: Gain technical knowledge
Although you may only provide sales, it is useful to gain some knowledge of the technology.
Gain knowledge of the following:
- Solar PV modules
- Inverters
- Batteries
- Mounting systems
- DC and AC systems
- System sizing
- Net metering
- Rooftop systems
- Safety
- Warranties
- Maintenance
If you provide technical services ensure you have adequate training and employ qualified staff where necessary.
Step 4: Identify quality suppliers
Do not only look at cost when identifying suppliers.
Consider the quality of the products, the quality of the warranty, lead time, technical support, return policy, documentation and compliance requirements.
Prior to buying solar PV modules, check the current requirements for the MNRE ALMM scheme and relevant product lists for eligible projects.
Step 5: Registration and compliance
Depending on the nature of your business and the type of business you are operating, different registration is required.
Some items to consider include:
- Business registration
- GST registration
- Udyam/MSME registration
- Local registrations
- Technical or electrical contractor requirements
- Requirements from DISCOM/State
- Registration for supplying to various government schemes
- Product certifications and standards
Just having one type of registration does not mean you can do all types of solar and electrical projects.
Step 6: Begin with a small service area
Begin with one city or several adjacent cities rather than an entire state.
This will make transportation, customer service, marketing and quality control easier.
Step 7: Build proof before scaling
Your first customers are vital.
Request genuine references and reviews from happy customers. Store information about services rendered, site visits, photos (as applicable) and customer feedback.
This kind of information can be used as a selling point.
Government Schemes Every Solar Entrepreneur Should Know
PM Surya Ghar: Muft Bijli Yojana
PM Surya Ghar is one of the most important schemes for companies providing services to residential rooftop customers.
The scheme has been approved by the government with an outlay of ₹75,021 crore and aims at promoting rooftop solar to one crore households. The government has confirmed that residential customers can choose service providers through the National Portal.
Government has announced that the scheme has crossed 40 lakh no. of beneficiary households as of June 2026 and aims to cover 75 lakh households by December 2026.
There is a great opportunity for service providers and installers. Entrepreneurs should also be aware of the technical and vendor specifications of the scheme as on date.
PM-KUSUM
PM-KUSUM aims at promoting the use of solar energy in agriculture. It includes both standalone solar pumps and solarisation of agricultural pumps.
PM-KUSUM is suitable for entrepreneurs in the following domains- Rural services, Electrical contracting, Maintenance of solar pumps and agricultural equipment.
ALMM
ALMM is relevant for sourcing of solar PV modules for projects that fall under ALMM.
MNRE has stated that modules listed in the applicable ALMM List-I can be used in specified government, government-assisted, net-metering and other schemes. The list is periodically updated. Businesses should check for the most current list instead of using a list provided by a supplier.
Common Mistakes to Avoid
- Starting with too much inventory: Having a large amount of inventory may appear professional but can cause cash-flow issues. Start with products that your customers desire.
- Choosing a business only because someone promises high profit: Solar is not a high-profit guarantee. Your profits will depend on many factors including customer acquisition, pricing, project execution, supplier costs, competition, warranty claims, labour, transport, taxes, working capital and more.
- Ignoring after-sales service: The relationship with a customer does not end when a solar system is sold. A customer might require assistance with cleaning, performance, faults, warranty or monitoring after the sale.
- Using poor-quality equipment: Low cost products can result in faults, complaints and warranty claims which can be expensive.
- Ignoring safety: Solar systems involve work on roofs and the use of electricity. If not installed correctly, this can result in electrical hazards, injury or damage to equipment. Technical safety should not be treated as an optional cost.
- Relying on out of date government information: The procedures for solar programmes and policies can vary. Before promising a process, approval or subsidy to a customer, ensure that the most up to date information is available from DISCOM, the state government, the scheme website and MNRE.
Conclusion
India’s rapidly growing solar industry presents opportunities that go beyond producing solar panels and constructing large solar farms. There are opportunities for solar businesses in installation, product sales, marketing, consultancy, training, pumps, water heating, cleaning, AMC and even sales.
When deciding on a solar business idea there are several factors to consider. These include your technical abilities, sales skills, local market demand, willingness to provide after sales service and your budget. Starting small can be an advantage as you will be able to assess the demand prior to making large investments in equipment or inventory.
Prior to making an investment research the local market, technical requirements, existing government regulations, potential suppliers and formulate a plan for acquiring customers. Do not select a solar business based upon a promise of high profits from an article on the internet.
The best Solar Business Ideas are those that address a market need and can expand through word of mouth, repeat business and reliable after sales service within the local community.
