Solar farming can be profitable, with average returns of 10-15% annually. Initial setup costs range from $800 to $1,200 per kW of capacity while operating costs are typically low. Revenue depends on local energy prices and solar irradiance levels.
Installation costs are dropping, too. As of 2025, solar panel installation per watt fell to just around $2.50 before incentives. This is on par with or cheaper than traditional plants in many regions, with a typical 11 kW residential system sticker price of $29,000, or $20,500 after applying federal and state tax credits.
Usually, power-purchase agreements, sale of energy directly to a power company or the local area as well as net metering are the ways through which solar energy farms operating on a commercial scale make money. A 1 MW solar PV system generating 1,825,000 kWh annually with 5 sun hours per day generates over $90k annually at a rate of $0.05 per kWh.
Investors can profit from solar through home systems to investing in ETFs and individual stocks. Emerging technologies like bifacial panels, perovskite cells, and integrated storage solutions are creating new opportunities. Solar energy harnesses the sun's light to generate electricity through photovoltaic (PV) cells or thermal solar systems.
While the system can bring a double-digit return on investment for some, for the hundreds of thousands who own apartments in shared buildings, it is not yet profitable. Over the past few years, it has become more and more popular for homeowners in Israel to set up solar panels on their roofs or in their yards — and for good reason.
A solar panel of about 100 square meters costs roughly NIS 70,000 to install and produces an average of 10 kilowatts of energy per hour. Assuming there will be about 1,700 to 1,800 hours of sunlight per year, at the current rate of about half a shekel per kilowatt, solar panels should bring an annual income of NIS 8,000 to 9,000.
When setting up solar panels, the first step is contacting a company that installs solar systems. Today in Israel, there are many companies of this type in the growing market, and it is worthwhile to conduct thorough market research and get recommendations from others who have already been through the process.
Another advantage to expanding the use of solar panels is that it reduces Israel's dependence on oil-produced energy, which in today's world affords great power to a fairly small number of countries, most of which are characterized by problematic regimes, to say the least.
Stand-alone solar PV mini-grids have installed costs in Africa as low as USD 1.90 per watt for systems larger than 200 kilowatt. Solar home systems provide the annual electricity needs of off-grid households for as little as USD 56 per year, less than the average price for poor-quality energy services.
In South Africa, the cost of installing solar panels varies significantly depending on several factors. On average, solar panel installation costs between R70,000 for a modest home to R350,000 for a larger home. These figures encompass the expenses related to equipment, labor, and other installation costs.
South Africa has seen a significant drop in solar panel prices, with costs falling as low as R3.50 per watt. This reduction—driven mainly by a decrease in global polysilicon prices and increased production—presents a substantial opportunity for businesses and consumers alike.
IRENA estimates that with the right enabling policies, Africa could be home to more than 70 gigawatts of solar PV capacity by 2030. The report discusses challenges in policy making and proposes a coordinated effort to collect data on the installed costs of solar PV in Africa, across all market segments.
