It is a long term investment, that is true and so we must think carefully if it is worth it.
However, it helps to know it is one of the few investments that saves us money year after year. What is also true is electricity rates go up year after year. A solar panel investment protects your business from price volatility. Depending on your location and whether you choose to buy or lease your solar system, you can lock in low electricity rates for 20 years or more, and even eliminate 100% of your electricity bill.
There are still a lot of questions to understand and that is why we do our best to help the house and factory owners understand the pros and cons.
