This is analogous to how mortgage interest is deductible from personal income taxes. This is used to compute the dollar benefit of the various tax incentives that solar projects are eligible for. Most inverters come with a life-expectancy of approximately 10 years, which is much shorter than the life of the panels themselves (25-30 years). With a PPA you pay a fixed price per kWh for power generated. The AC size of your solar energy system will always be larger than the DC system size, as the solar modules produce DC power and then utilize inverter(s) to convert it to AC, which is what our home electrical appliances use. Input the revenue on that is assumed on the inputs tab of the project finance model for solar. Solar panel efficiency decreases over time and this is referred to as degradation. LCOE = lifetime costs / lifetime electricity produced, https://en.wikipedia.org/wiki/Cost_of_electricity_by_source#Levelized_cost_of_electricity. This can significantly impact the value and payback of your system as this number is used to value any energy the system produces that you do not use instantaneously. For example, if the ITC is 30% of the system cost, then the depreciation basis will be reduced by half of the ITC amount (15%) for a final basis of 85%. Solar panels typically have 25 year performance warranties; PV systems being installed can be expected to last 30+ years. Wed love to hear from you. Buyout cost: 26,271.06 + tax = 28,438.42 Current PG&E electric rates: E-1 at $0.24/kWh; under NEM1 rules. For more information, explore: Please enter the initial capital cost of the project. You can calculate the DC size of the system yourself by multiplying the number of panels by the panel wattage (located on the modules themselves, or on the spec sheet), e.g., 20 panels x 320 watts each = 6,400 watts DC. Depending on the level of coverage, the cost of O&M is usually in the $10-$25/kW/year range. Solar Renewable Energy Credits (SRECs) are a performance-based solar incentive based on the solar electricity generation of your system. LCOE stands for Levelized Cost of Energy and is a metric that represents the lifetime average cost of electricity produced by a solar installation, taking into account all revenues and costs. It is recommended to error on the side of a lower escalation rate to ensure the model is providing a worst case scenario and not overpromising financial cost and payback.

Most PPA agreements have buyout provisions: the ability to terminate or buy out the contract before the full term. Solar Renewable Energy Credits (SRECs) are a performance-based solar incentive based on the solar electricity generation of your system. The year by year benefit of the system taking into account all revenues and expenses, The cumulative economic benefit of the system over its lifetime, The yearly avoided cost due to the electricity produced by the solar installation, A comparison of the avoided rate of grid electricity vs the levelized cost of solar energy, A comparison of the avoided electricity rate vs the PPA rate, Remember me?
