Solar energy is a renewable source of energy that can be used anywhere on Earth. It produces significantly less greenhouse gases than fossil-fuels.

Photovoltaics cells convert sunlight into electricity and power devices such as calculators, power stations, spacecraft that power the International Space Station.
1. It is a renewable source of energy
Solar energy is an inexhaustible renewable source of energy derived from sunlight. Unlike many energy sources that rely on burning fossil fuels for production of electricity, solar power does not emit greenhouse gas emissions or deplete resources over time.
Solar technology uses sunlight to convert it directly or indirectly into electricity, either using photovoltaics (PV) or concentrated solar power systems with lenses or mirrors directing sunlight onto central thermal power plants. Photovoltaics convert solar radiation into an electrical current, while concentrated solar power systems direct the sunrays to central thermal power plants where they are used as heat.
Solar panels produce more electricity than you require, the excess goes directly back into the mains grid for other households to use – an effective way to lower energy bills while helping the environment. Solar energy can also provide relief to people living in remote areas without access to other forms of energy; independent systems can even be deployed worldwide and improve quality of life for many without regular access.
2. Cheap
Solar energy can save you money on electricity over time. However, the initial investment could be significant. Leasing options can help you reduce the initial cost if costs are an issue.
Solar power has become more affordable with technology advances and economies of scale, and is now cheaper than new fossil fuel power plants, according to multiple reports.
Shop around to get the best solar system pricing possible, keeping in mind wattage and size costs may impact cost comparisons; purchasing two identical 200W panels could cost less. In order to maximize savings over time it’s also important to calculate average electricity usage in your area so you can purchase the appropriate size system based on what works for your household’s consumption needs.
3. The product is eco-friendly
Solar energy provides an environmentally-friendly alternative to fossil fuels. It reduces greenhouse gas emissions like carbon dioxide and other air pollution from entering our atmosphere and water supply. Solar power also reduces the emissions of nitrous oxides and sulfur dioxide, as well as particles that can pose a threat.
Solar power reduces the demand for fossil fuels and coal, which means less drilling and burning operations that cause deforestation. Solar panels are made from solar cells, which require a lot of energy to mine and manufacture. However, they produce far less emissions than other sources of electricity.
Since 2009, solar panel installations for homes have seen their costs decrease drastically and many homeowners qualify for government rebates and tax credits to offset initial installation expenses – making solar an affordable way to both save money and reduce carbon emissions simultaneously. Furthermore, modern systems use batteries to operate even during bad weather conditions!
4. It is scalable
Many people have claimed that solar, wind and other renewable technologies are close to a tipping-point where they may become the dominant source of energy. They base their claim on the notion that these forms can quickly be installed to meet different grid sizes or production capacities.
Over the years, solar power costs have decreased significantly. This gives homeowners and businesses/governments alike a chance to save money. Installing solar energy systems may even lower operating expenses.
The World Bank Group launched Scaling Solar to help meet the needs of clients and enable faster deployments of grid-connected, privately funded solar projects with competitive tariffs in Africa. It provides speed, certainty and competitive tariffs through its standard processes and documents which facilitate quick preparation, tendering and financial closure.
