EcoWatch's Loudoun Valley Estates, VA Solar Cost FAQs

How much does it cost to install solar panels in Loudoun Valley Estates?

This is a difficult question to answer precisely, because the cost depends on many factors. Broadly speaking, it costs about $17,950 for a 5-kW system and $35,900 for a 10-kW system after the ITC is applied. You can expect to pay more if you want additional solar equipment or higher quality panels, or if you have higher-than-average energy consumption. On the other hand, you can spend less if you go with a smaller solar panel system or cheaper solar panels.

Should I lease or buy solar panels in Loudoun Valley Estates?

Leasing solar panels can be an option if you are unable to pay upfront or secure a solar loan, but since you don’t own the system, you don’t have access to many solar incentives. Also your home value won’t increase, so you’ll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most savings from going solar.

How much can I save on electricity bills after installing solar panels?

Solar panels can potentially eliminate your electricity bills depending on your location and the efficiency of your system. Even if it doesn’t get rid of them completely, you can save a lot of money on your bills, about $905.80 per year.

How many solar panels do I need to power my home?

To figure out what solar panel system size you need, you should find out how much energy your home uses and how much sunlight your home gets. For a general estimate, however, since each panel can generally produce about 250 to 400 watt-hours per hour, the average house will need 20 to 35 panels.
