The Five Most Frequently Asked Questions About Solar Energy

Solar Panels

Adam answers the five most frequently asked questions about solar energy. More and more people are switching to solar energy and are therefore saving considerably on energy bills. Yet we notice that there is still much ignorance about solar systems. We are happy to share our knowledge and provide answers.

Is solar energy expensive?
That depends on the surface on your roof. Now it is on average 8 cents per Kwh. But prices are falling fast. In the last ten years the price has become eight times as cheap! With the current interest rate that banks give for your savings, it is almost always wiser to invest money smartly. Solar panels are relatively expensive to purchase, for you do not have to purchase anything for other energy yourself and you only pay for the energy that you purchase. The return is quite high. For private individuals it is comparable to 6% savings interest. In short: the cost goes for the benefit.

How much solar energy is needed for an average household?
An average household uses around 3000 kWh of electricity per year. For this power consumption you need 12 average solar panels (12 x 260 = 3120). But this is an average of large and small households. It is fairly easy to calculate what your household needs. Moreover, you do not have to generate 100% of your energy needs yourself.

Do you need a suitable roof to generate solar energy?
You must of course have space, a flat roof or a roof with a slope and not too much shade. One roof is also more suitable than the other due to the direction. A ‘south-facing roof’ provides more return. But even if you don’t have a suitable roof to install solar panels on, there are still plenty of options. At least if you think it’s important to do something with solar energy. The options vary from buying panels on a roof in the neighborhood to purchasing electricity from other consumers with solar panels.

Is there enough sun in most countries for solar energy?
Very little sun is of course not that practical, but too much sun and warmth either. The warmer it is, the more resistance. In our country we have a temperate climate with enough hours of sunshine. In short: we could potentially be a progressive solar panel country. Just a technical side path: a solar panel that also works well with clouds is built with PERC cells . They ensure a better flow of energy so that less is lost. They do this by pointing the way for electrons.

Can you also generate solar energy if the sun is not shining?
Direct sunlight is not necessary to generate energy. Solar panels also simply provide power when it is cloudy or rainy. But … On a clear blue summer day, your solar panels naturally deliver the most!
