The disadvantages of solar energy are the high initial cost, the inability to work on any type of roof, and it can be difficult to find a local installer depending on where you live.
Why solar panels are not profitable?
But there is an important obstacle to their profitability: a decline in revenues. Adding wind and solar power to the grid tends to drive down the price of electricity over the time they generate. On a sunny afternoon in California, the production of solar power can reach such a high level that the price of electricity drops to zero.
How much do solar panels save in 2021?
Due to the current federal tax break for renewable energy systems (26% of total system and installation costs), most customers will save over $ 3,000 if they opt for solar in 2021 or 2022.
