Сколько денег я могу сэкономить с 20 солнечная система кВт?

Сколько стоит солнечная рассрочка, но настоящий вопрос заключается в том, сколько вы можете сэкономить. Солнечная установка - большие деньги, но если вы можете сэкономить еще больше денег в течение срока службы установки, тогда это того стоит, Правильно? Хорошо, создание 20 Система кВт означает большую экономию! Keep reading to see how.



To determine the economic savings of a 20стоимость солнечной системы квт, we need to contrast your overall solar installment price to your overall expense of remaining to acquire electrical energy from the utility. Most in the solar industry generally think a solar setup to last between 20 а также 30 годы, so we’ll split the difference as well as use 25 years in our calculations.



As we saw, your total setup cost for a 20 kW planetary system is $41,020 after the 30% federal tax credit scores. Your setup expense could even be reduced if your state or energy uses additional motivations, but we will not consist of those below.

For this example, let’s claim you stay in North Carolina, where the ordinary utility rate is $0.1178 per kWh. (Click the web link to locate your state’s average energy rate!).

$ 41,020 as well as $0.1178 per kWh. Just how do we contrast these two extremely various prices? We need to contrast the same quantity of electrical power! To do this, we need to understand the number of kilowatt-hours of electrical power a 20 kW system generates in North Carolina. Allow’s go to the National Renewable Energy Lab’s no-cost online Solar Calculator, PV Watts, to discover.

We connected our numbers in PV Watts and also discovered that a 20 kW installment in Charlotte, North Carolina, will certainly produce 28,211 kWh annually. It would set you back $3,323 if we bought that quantity of electrical energy from the utility!

So currently we know a 20 kW solar system produces 28,211 kWh yearly (and that 28,211 kWh would cost $3,323 from the energy) yet what concerning the complete price over the following 25 годы? We require to determine this amount!

Initially, photovoltaic panel manufacturing goes down about 0.08% every year due to age, staining, и т.д, so after 25 years your solar installation will certainly have produced concerning 641,544 кВтч!

Utility rates generally increase about 2.5% every year usually, so we additionally need to include this to the mix. After 25 годы, you would will have invested $116,078 acquiring 641,544 кВтч.

Subtracting your initial solar financial investment from $116,078, we find that by mounting a 20 kW solar setup, you can conserve $75,058 over 25 годы! If electrical energy is more pricey in your location, or if your city or state uses solar refunds, your savings could be even higher!

So if you’re considering installing a huge solar installation, chances are high that you will certainly save a great deal of cash over the following 20 к 30 годы. For a harsh price quote of your very own cost savings, comply with the actions over!
