How Does Solar Energy Work?

Energy from the sun is collected and converted into electricity by photovoltaic solar cells, better known as solar panels. This technology has been around since the mid-1950 however, the technology and efficiency have come on leaps and bounds since then. Each cell consists of two wafer-thin layers of silicon of opposing charge, one positive and one negative. When sunlight hits the cell, it causes electrons to break free from atoms within the cells, these move due to the electric field around the cells and this creates an electrical current.

This may all sound a bit complicated but it’s actually quite a straightforward process, the result of which is the generation of electricity that can be used to power devices around your home, it’s no different to the electricity you get from your mains power supply.

How Can Solar Energy Power Your Whole House?

Can solar panels power an entire house? The answer is Yes they can. If you’d like to see some examples, check out our pool villas in Phuket – Thailand, they’re entirely powered by solar, 100%.  There are a few things you need to take into consideration when deciding what kind of set-up to have, realistic expectations to be able to power your whole house from solar energy. What kind of power output you’ll need, how many panels to go for etc., but it is a 

The location and aspect of your home will have a big impact on the amount of energy that can be generated, the correct placement of your solar panels in the best place available to you can make a big difference to your energy output.

Is Thailand Good For Solar Panels

Thailand is in a great location for solar panels, being so close to the equator it receives a constant 2,600 hours of sunlight each year. With only a slight variation between day length in June and December, it makes sense to choose solar power as an energy source in Thailand due to the reliable and stable levels of sunlight. The sun being almost directly overhead also increases the output of the solar panels as peak capacity is reached a high proportion of the time, in fact Thailand is one of the best countries in the world for solar power.

What Type And How Many Solar Panels Does Your Home Need?

There is a huge range of makes and quality of solar panels available on the market today and it’s advisable to shop around and get as much professional advice as possible before making your final decision. A site visit will probably be required for them to assess your home and discuss the best placement of the panels with you.

Obviously, there are a lot of variables to take into consideration however, as a basic rule of thumb, most panels are around 250 watts per panel with an average output of around 400 watts per day per panel in good conditions. An average home these days takes around 6,000 watts a day to run, so on average, you’ll need to be looking at 15 A-series panels to go ‘off-grid’. Of course, your needs may be higher or lower and your location and aspect play a big part. But it’s definitely possible.

Factors That Impact the Ability to Reach 100% Coverage With Solar Energy

In order to get you ‘off-grid’, your solar engineer will take a look at how much electricity you use throughout the year. Your demands change through the seasons and this has to be taken into account when working out what kind of system you’ll need. The easiest way to do this is to look at your energy bills. Winter months have different demands to summer months, you’re indoors more of the time and you’ll use more for heating, etc., but during the summer you may use the air conditioning more. All of this will be evened out and taken into account.

You’ve probably seen solar panels on people’s roofs, this is a common solution to the problem of where to situate your panels. However, not all roofs are suitable. A south-facing roof with an incline of between 30° and 45° is absolutely perfect; however, not all houses are built with this in mind. In some instances, the best place for the panels is on the ground in which case you’ll need to have an area of between 320ft2 to 1,200ft2 for a 5 kW to 20 kW set up. Cast shadows also have an impact, trees may need to be trimmed but permanent fixtures which cannot be moved such as chimneys or other buildings will have an impact on your energy generation.

Is It a Good Idea To Invest in Solar Panels for Your House?

Investing in solar panels is a wise decision for any homeowner who wants to lower their energy bills and gain more control over their energy consumption. Especially if you live where it is sunny where traditional electricity sources are not required thanks to the conversion of sunlight into energy by solar panels. Solar panels can help you save money over time because they eliminate the need to deal with rising or variable electricity costs. They can also help you reduce your carbon footprint significantly.
