What are common factors to consider before hiring a Greenwich solar installer?
When selecting a professional solar panel installation company, first review these key considerations.
What size system do you need?
Your solar panel system's size is influenced by your home's energy consumption and the system's production capacity. Larger homes use more electricity and might require bigger solar setups. An undersized system might not manage to fully energize your house.
Is your home subject to specific permits and regulations?
Required permits and local or state laws could affect your solar project. Be sure to secure necessary permits through your local building department and arrange an inspection.
Does your home get enough sunlight access?
Not all homes receive the same amount of sunlight. Trees, rainfall and severe weather conditions in your area can impact sunlight access. If your home doesn’t get enough sunlight, then you may require extra panels with a higher wattage.
Do you need a solar battery?
Numerous solar panel systems offer a battery. Solar batteries store extra power, which is incredibly helpful when you want to prevent power loss when there's no sunshine. Installing battery storage may increase the cost of installation.
Which type of solar panel do you want?
You have choices among solar panel types, as they differ in design, life expectancy and efficiency. These elements can change the cost, when you'll need to swap panels and the amount of roof area you'll need.
