Solar photovoltaic (PV) systems are not for the most part difficult to understand. Solar panels, being the main component, gather the sunlight and convert it into electricity. The direct current (DC) generated by the panel is channelled into an electrical device called an inverter, where the DC is converted into alternating current (AC) which can be used in the home.
It is the general consensus among solar firms that simplicity pays. Generally most customers will prefer uncomplicated systems installed on their roofs, since this usually brings the best return on investment, with low outlay costs. On the other hand, as you become more sophisticated with these types of system, costs quickly rise and unscheduled maintenance of the system can eat into the profits you would otherwise amass. A customer then is advised to utilise demonstrated, field-tested equipment that is designed to meet the needs of a specific situation so as to acquire the best return on investment.
Some interesting benefits of solar electricity
A residential PV system will allow a property holder to generate a considerable amount of his or her entire yearly electrical energy requirement. To do this a Grid-tied system is used where the home is coupled permanently to the Grid, permitting any required power needs above that which the solar system can generate whilst also being able to feed back into the Grid at times when energy is not being used by the householder. Using this type of system batteries are not necessary to store the power generated, saving money in initial system costs. Dwellings having a Grid-tied solar-electric system will have AC electricity simultaneously coming from and going to the Grid. To do this the system uses a bi-directional electricity meter which monitors how much electricity runs in each direction. This is an uncomplicated system which does not create noise, has no emissions and hasn’t any moving parts.
Apart from having to depend less on non-renewable energy systems, solar power also offers proprietors reliable, static, energy costs which in turn can eliminate the concern for unavoidable electricity rate increases.
The electricity obtained from solar power is now conveniently used for illumination and to power home appliances across the UK. And these days thousands of homes and businesses are powered by these PV systems.
As a footnote, it’s appealing to know that direct sunlight is not necessary for solar panels to produce energy – some energy can even be generated on a cloudy day.
