Solar Panel Installation in Tenby

Solar cells , also referred to as photovoltaic cells (PV), absorbs energy from the sun and converts it to generate electricity. This, however, should not be confused with photovoltaic thermal cells or PVT which operates to generate heat for water in homes. Solar cells are linked electrically and also carefully organized into a large frame which is popularly called solar panels. Generally, solar cells are produced or made of silicon semi conductors which works to absorb sunlight and then turn it into electricity for use at a home. A solar panel comprises of either 60 or 72 solar cells which are electrically interconnected in series and parallel and also positioned in between glass and plastic which is then framed.

At present, solar panels incorporated for residential or domestic purposes only possesses the capacity to make use of only about 20 percent of the sunlight they’re able to absorb and convert it to electricity - also called solar efficiency. Available in the market are also a wide range of solar cell available for both industrial and commercial purposes. This type of solar panels have an efficiency rating of about 40 percent which will also automatically make them more costly than the domestic types.

One great thing about the solar industry is the fact that it keeps improving in such a way that raises both its efficiency as well as overall quality. And with further research and development, this is expected to even increase as the years go by. What’s more? As these aspects keep rising, it’s also expected that the solar panels price should be on a decrease. That way, they’ll become available to a wider range of individuals who’ll also like to save money on electricity bills and go greener.

If you’re looking to purchase and install a solar system for your home or property, then knowing the amount of energy a solar panel can produce can go a long way to help you determine just how much solar panels that’ll be needed to power your entire house. In this article, we’ll give you an idea of the amount of energy that can be generated by a solar panel to help you make informed decisions going ahead.

First and foremost, you should note that each and every solar panel is rated by how much direct current power they’re able to generate under standard testing conditions. The output of a solar panel is given in watts units (W) and it stands for the theoretical power generation of the panel under direct sunlight as well as temperature conditions. Generally, several domestic solar panels possesses power output ratings which ranges from 250 watts to 400 watts. And as you would have expected, the higher power ratings are preferable when compared to the lower power ratings. What’s more? The total wattage of your solar panels will greatly influence a major part of your overall solar system cost.

Assuming you’re able to get just about 5 hours of direct sunlight every day, you can determine the output of your solar panel in this way - 5 hours x 290 watts ( wattage example of a premium solar panel) = 1450 watts-hours or approximately 1.5 kilowatts per hour (kWh). hence, the individual solar panel output in your array should be able to generate about 500 to 550 kWh of energy every year. This is sufficient energy to power some small appliances without problems.

Solar panels are a great source of energy with numerous benefits that comes with it. However, the main thing that puts off most homeowners or potential buyers is the fact that the equipment are usually very expensive. So if you’re planning to purchase solar panels to be installed in your home, then you’d probably want to know if it’s actually worth the investment or otherwise. In this article, we aim to give you a good insight into how solar panels works and if its a viable investment.

Generally, the length of time it will take for your solar panels to payback and whether you’ll be able to make money from them will be based on the following factors:

✓ The solar panel PV system’s cost.

✓ The amount of the generated electricity that you’re able to use.

✓ Whether as well as the amount you’re paid to the electricity you’re able to generate and export.

To know whether your solar panels are truly worth it, then a higher initial cost to fit the system will require to be settled with the amount you’re able to save through the use of the renewable electricity it produces, rather than making purchases from your electricity company. In other words, the more renewable energy you’re able to use, the more savings you make. If you’re registered for the FIT and paid per kWh of electricity produced, for 50 percent of that, which is assumed to be exported to the grid. Therefore, if you’re able to use more than 50 percent, you’ll be able to benefit from the investment.

In a similar way to other major home improvement projects, some specific requirements must be met to allow for the installation of solar panels. The main reason why these standards and regulations were established is to minimize the risk of the solar system becoming an issue or potential hazard in the unforeseeable future. So if you’re thinking about buying and fitting new solar panels, you’ll probably want to know whether or not you’ll require to submit a planning permission application for approval before you can proceed.

Generally, solar panels are covered under what’s called “Permitted Development” which gives you the freedom to install your solar panels without having to apply for a planning permission. However, there are some exceptions to this rule. These exceptions include if your house is a listed building or if your house is located within a conservation area. In these exceptional cases, it’s possible that you’ll need to apply for a planning permission, but this will largely depend on the discretion of your Local Planning Authority. What’s more? Solar panels are usually subjected to normal building regulations which includes examining the roof to make sure that it can support the additional weight. You can call in a MCS certified installer to carry out this check for you.

In order to install your solar PV on your roof, you must follow these guidelines:

✓ Your solar panels shouldn’t go beyond the highest point of the roof (excluding chimneys).

✓ The solar panels shouldn’t project beyond 200mm off the roof’s edge.

✓ The solar panels should be removed once they’re no longer used to produce electricity

✓ The solar panels should be installed such that the area and building’s appearance change is minimized.
