Roof Compatibility

Before installing solar panels, it is important to consider the direction and angle of the roof that the panels will be installed to capture the most amount of sunlight. As long as there is enough access and space, solar panels can be installed on any roof. However, the complexity and cost of installing solar panel deviates with the composition and design of the roof.

Payment Options

Solar Loans – A third party solar financing company will take care of your loans and mortgages from the federal government to finance your solar panels. However, you have to check carefully for the interest rates and balance the prices if it is worth it.

PPA – Power Purchase agreement is a long term contract between the solar provider and the consumer. Instead of paying to lease the solar panel, you settle to buy the power generate by the system at a set per kWh.

Purchase – When you purchase a solar panel you are maximizing the financial benefits and investment. Not just for lower electricity fee but also buying a solar panel system can increase the value of a home.

Solar Lease – Just like PPA, you don’t buy the solar panel, instead you just rent the system without worrying for the maintenance of the solar panel. With solar lease, you agree to pay for the fixed monthly lease charges which is calculated by the amount of electricity that system’s produce.
