A photovoltaic (PV) system is a series of solar panels (or modules) connected to inverters which change the electricity from direct current (DC) produced by the panels into alternating current (AC), making it compatible with your home’s power system.
Using solar power means you’re buying less electricity from the grid than you normally would, or you might even be selling the excess back - either way you’re saving money.
Solar Module (Panels) warranties explained
Solar panels will produce electricity for a long time, much longer than your payback period, which is one of the great reasons to invest in them. Solar panels have two types of warranties. They have a 25 to 30 year linear performance warranty, which means that the manufacturer guarantees that their efficiency cannot drop below a certain percentage (usually 85% at the end of lifetime). And a manufacturing warranty that covers manufacturing defects, ranging from 12 - 25 years.
Industry Leading Modelling
We use satellite data, drone imagery, LIDAR (laser scans from space!) and physical measurements to create a highly accurate digital model of your roof down to every last vent. We also model nearby trees and structures to be able to accurately simulate shading conditions. Using predictive weather and sun path models, the software builds an irradiance map that informs placement of the solar panels (which is both a science and an art, in our opinion).
A model or forecast is only as good as the data that you use to make it - this is why we focus on gathering detailed data that we need before designing a solar system for your home. This information usually includes:
Simulating and Forecasting
We then move onto the process of forecasting the electricity production and financial performance of the solar system in order to create a customized proposal and quote. This takes into account dozens of factors including:
