A number of factors are used to calculate the projected performance for your solar installation. Ensure the quote you obtain documents the following:
- Estimates the total costs of the solar equipment;
- Sets out the approximate life of the components (manufacturer’s warranty period).
- Indicates the potentially significant costs for replacement parts such as inverters or collectors and control systems.
- Accurately assesses the solar irradiation and energy production, considering statistical highs and lows caused by fluctuations in weather.
Also, consider including monitoring equipment with your system to track its performance and ensure its optimal performance.
