Solar energy has had a reputation of being an expensive form of renewable energy, due to the high average cost of solar panels as well as high installation and maintenance costs. But as technology develops, and a lot of research is being conducted in the field of solar energy, the costs have shown to be dropping. How much do solar panels cost today, and how high are the solar panel installation costs?
Today efficient provision of energy is crucial, and since non-renewable sources of energy will eventually be depleted, we must transition to other, renewable sources. The four main sources of non-renewable energy today are oil, natural gas, coal and nuclear energy – some of which also have a substantial negative impact on the environment. However, there are cleaner options – renewable energy, that naturally will not run out or be depleted. The main sources today are wind energy, hydropower, biomass, geothermal energy, and of course, solar energy.
