What is a Solar PV system?
A photovoltaic (PV) system is comprised of one or more solar panels combined with an inverter and other electrical and mechanical hardware that use energy from the sun to generate electricity. Solar PV systems can be installed on rooftop areas of residential, commercial and industrial buildings.
Blackwood Heating Ltd, provides a full assessment, specification, and installation service in Hartlepool, ensuring that your renewable heat solution is tailored to your requirements.
How does this system work?
The light from the Sun, made up of packets of energy called photons, falls onto a solar panel and creates an electric current through a process called the photovoltaic effect. Each panel produces a relatively small amount of energy, but can be linked together with other panels to produce higher amounts of energy as a solar array. The electricity produced from a solar panel (or array) is in the form of direct current (DC). Although many electronic devices use DC electricity, including your phone or laptop, they are designed to operate using the electrical utility grid which provides (and requires) alternating current (AC). Therefore, in order for the solar electricity to be useful it must first be converted from DC to AC using an inverter. This AC electricity from the inverter can then be used to power electronics locally, or be sent on to the electrical grid for use elsewhere.
