What are common factors to consider before hiring a St. Louis solar installer?
Take time to reflect on these questions prior to hiring a solar panel installation company.
What size system do you need?
Your solar panel system's size is contingent upon 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?
Your solar plans may be impacted by specific permits and state or local laws. You must get proper permits through your local building department and coordinate an inspection.
Does your home get enough sunlight access?
Not every house gets the same sun exposure. Local tree coverage, precipitation and extreme weather conditions can limit sunlight. If your home lacks adequate sunlight, you may need additional panels with increased wattage.
Do you need a solar battery?
A solar battery allows the storage of extra power in solar panel systems. This is especially useful when you're trying to prevent power loss under cloudy skies. The extra battery storage could raise the overall installation cost.
Which type of solar panel do you want?
Multiple solar panel varieties exist, each differing in design, life expectancy and efficiency. These factors affect pricing, the rate of panel replacement and the amount of roof space you'll need.
