Solar panel efficiency is the amount of sunlight (solar irradiance) that falls on the surface of a solar panel and is converted into electricity. Due to the many advances in photovoltaic technology over the last decade, the average panel conversion efficiency has increased from 15% to over 23%.
You can calculate your total solar savings by subtracting the amount you pay for solar (including tax incentives) from what you would have otherwise paid for electricity. How much do solar panels cost? Solar is an up-front investment. After you pay for the equipment and installation, your system will produce free electricity for years to come.
Most solar shoppers save between $28,000 and $120,000 on electricity over the lifetime of their solar panel system. We'll explain how to save money with solar, and how to calculate your estimated savings. Solar panels are an expensive initial investment but provide significant savings on energy bills over time.
Solar panel efficiency is measured under standard test conditions (STC) based on a cell temperature of 25 ° C, solar irradiance of 1000W/m2 and Air Mass of 1.5. A solar panel's efficiency (%) is calculated by dividing the module power rating (W), or Pmax, by the total panel area in square meters at an irradiance level of 1000W/m2 (STC).
The savings from a solar panel system can be looked at on a monthly basis and over the lifetime of a system. Monthly savings will depend on how much energy you use and how much energy is offset by your solar system. We strive to design each system to offset 100% of your electricity usage.
Increasing the panel size can improve efficiency by creating a larger surface area to capture sunlight, with the most powerful solar panels now achieving well over 700W power ratings. What are the most efficient solar panels? At present, monocrystalline panels are the most efficient type available.

Adequate solar panel planning always starts with solar calculations.Solar power calculators can be quite confusing. That''s why we simplified them and created an all-in-one solar panel calculator. Using this solar size kWh calculator, together with savings and payback calculator, will give you an idea of how to transition to a solar panel-based system for your house.
The cost analysis for solar panel installation varies but expect an initial investment of around $8,000. Annual maintenance is about $200, while annual energy savings can be up to $4,000.
Monthly savings will depend on how much energy you use and how much energy is offset by your solar system. We strive to design each system to offset 100% of your electricity usage. Over the lifetime of a system, solar will pay for itself and then some. It''s not uncommon to see a system pay for itself twice over during its 30-year lifespan! That''s some great return on investment (ROI).
