- Long-Term Savings
Three factors that shape your long-term solar savings
The initial system install cost
We install our solar systems inhouse to minimize the installation costs. We ensure that the optimal solar solution is designed in order to keep installation costs low. We don’t up-sell larger systems that are excessive for a household’s needs. We design systems that have a fast payback period .
Savings on your power bill
We craft the perfect solar solution to target your energy consumption patterns. Solar systems generate power to be consumed in house or sold back to the grid. We can significantly reduce or eliminate your monthly power bills.
Extended long-term power generation
We design quality solar systems that are guaranteed to last for decades. A solar system’s longevity is crucial because it ensures that after the initial investment is repaid through savings on electricity bills, the system continues to produce energy for many years.
