For the exact solar panel computation, take your location, weather conditions, panel size, system efficiency, and derating factor as discussed in the blog into consideration. Divide the total monthly energy needs (1000 kWh) by the number of days in a month and divide by the panel output to get a precise estimate.
The cost of the electricity generated by a PV system is determined by the capital cost (CAPEX), the discount rate, the variable costs (OPEX), the level of solar irradiation and the eficiency of the solar cells.
The average cost of BOS and installation for PV systems is in the range of USD 1.6 to USD 1.85/W, depending on whether the PV system is ground-mounted or rooftop, and whether it has a tracking system (Bony, 2010 and Photon, 2011). The LCOE of PV systems is therefore highly dependent on BOS and installation costs, which include:
The efficiency of a solar panel refers to the amount of sunlight that is converted into usable energy. Panels with higher efficiency are able to generate more power from the same amount of sunlight. Therefore, it’s vital to consider the solar panel efficiency. Below is the formula to calculate it: Efficiency (%) = [ (Pmax ÷ Area) ÷ 1000] × 100%
Divide the actual solar panel capacity by the capacity of a single panel to determine the number of panels needed. For example, if your average daily energy consumption is 30 kWh and the system efficiency is 80%, and you have an average of 5 hours of sunlight per day, you would calculate your daily energy production requirement as follows:
On average, solar panels cost $8.77 per square foot of living space, after factoring in the 30% tax credit. However, the cost per square foot varies based on the size of the home. For example, the post-tax credit cost of solar panels for a 2,500-square-foot home is around $20,000 for a rate of $7.96 per square foot.
