First and foremost, you’d want to note that prices for solar panels have fallen a whopping 45% over the last five years. Texas data shows that the average solar installation cost in the state ranges between $11,000 and $16,000, depending on your home’s energy needs. Adding solar power storage batteries such as Tesla Powerwall can as well raise these costs. However, adding a solar PV backup battery gives you complete control of where you get your power. Furthermore, you can additionally offset your initial installation costs by taking advantage of different solar incentives available. Also, there are various financing options for you if you don’t have the total upfront costs to cover your solar installation.
