We've already vetted all of our installer partners, and keep a close watch over their performance to ensure their installations and customer satisfaction are up to the levels that you–and we–expect.
The government incentives have also contributed to the curtailment of solar energy, as many of the solar projects have been built in northern and western regions of China where there is a low demand for electricity and a lack of infrastructure to transfer energy towards China's main power grid.
Reports of large Chinese solar manufacturing companies using forced labor from Uyghurs of Xinjiang to produce photovoltaic cells have appeared. Reports for forced labor being used to acquire polysilicon, a key component of solar panels, have also emerged.
While many developed countries that produce photovoltaic cells have properly disposed of or repurposed wasted solar cells, many Chinese firms have not adopted the practice recycling solar panels and waste. Non-hazardous materials have also been dumped instead of repurposed, further contributing to waste.
In 2025, the typical cost of commercial lithium battery energy storage systems, including the battery, battery management system (BMS), inverter (PCS), and installation, ranges from $280 to $580 per kWh. Larger systems (100 kWh or more) can cost between $180 to $300 per kWh. How does battery chemistry affect the cost of energy storage systems?
In 2025, the typical cost of a commercial lithium battery energy storage system, which includes the battery, battery management system (BMS), inverter (PCS), and installation, is in the following range: $280 - $580 per kWh (installed cost), though of course this will vary from region to region depending on economic levels.
Investing in commercial battery storage systems now offers benefits such as shorter payback periods, energy independence, reduced peak power costs, and achieving sustainability or carbon neutrality goals faster. Additionally, government incentives make systems more affordable.
Government incentives (e.g., tax credits in the U.S. and Europe) make systems more affordable. For example, in 2022, a 100 kWh system could cost $45,000. By 2025, similar systems could sell for less than $30,000, depending on configuration. Why invest now? Shorter payback - payback periods for today's commercial systems are typically 3-5 years.
Solar energy offers a cost-effective, eco-friendly, and long-term solution to reduce electricity bills and ensure energy independence. One of the most common questions homeowners ask before switching to solar is: “How much do home solar panels cost in Sri Lanka?”
The payback period for industrial solar installations in Sri Lanka typically ranges from 3 to 4 years. Efficient project designs and use of high-quality components contribute to favorable ROI. The upfront costs for a factory-sized solar installation can be significant.
Government Incentives: Although there are no specific subsidies for solar systems in Sri Lanka, homeowners can deduct a portion of installation costs from their taxable income—the solar industry benefits from tariffs supporting energy adoption.
Solar Panels: These are the most visible components of a solar system. Solar panels convert sunlight into direct current (DC) electricity. The efficiency of these panels can vary, but in Sri Lanka, with its average solar irradiation of around 4.5 to 5.5 sun hours per day, solar panels can generate significant amounts of electricity.
Solar panel installation cost averages $27,172 for a standard home, with most homeowners spending between $18,351 and $36,399. Prices vary based on system size, panel type, and installation complexity. Expect to pay $2.50 to $3.50 per watt installed, with larger systems offering better value per watt.
Ultimately, many factors figure into the price per watt of a solar system, but the average cost is typically as low as $2.75 per watt. This price will vary if a project requires special adders like ground mounting, a main panel upgrade, an EV charger, etc.
According to studies by the U.S. Department of Energy, the all-in cost of a home solar panel system is between $2.74 to $3.30 per watt. 1,2,12 This figure includes the solar panels, the installation, and other expenses.

Using these numbers, an average-sized 8-kilowatt residential solar system would cost between $21,900 – $26,400.
