Solar contractors should be prepared to explain some of the facts that every customer should understand.
Many homeowners don’t understand the relationship of solar panel size to wattage and energy output – and to cost.
- The price of the solar panel is related to its size and wattage. Larger panels generate more wattage.
- The main issues are that the solar system has sufficient wattage to power the household appliances and that the panels will physically fit onto the house’s roof.
- The type of solar cell helps determine the size and cost of the panel. Film panels are less expensive than monocrystalline and polycrystalline panels, but they need more roof space
- A 100 watt solar panel will generate 100 watts of electricity an hour while a 200 Watt panel will produce 200 watts per hour. So, a 200 watt panel should cost approximately twice a 100 watt.
