Solar Design and Installation
The world has been shifting from the use of fossil fuel over time and a lot of people are now embracing green, renewable power sources. One of the most popular of these is the solar power system. This system is basically the harnessing of the sun radiations to power appliances and equipment.
When making Solar design and installation, there are some things one need to take note of and make provisions for. These things affect things like the effectiveness of the solar panel, the longevity and power output. In this article, we will look into this and proffer tips on getting optimal value for your money.
When installing a solar electric system, the ultimate goal is to ensure that the system is sited, sized, installed and maintained appropriately. The following things are to be considered when coming up with the design:
What are your electricity needs?
How big must the system be to cater for your needs?
How much sun light do you get?
Where will the system be installed and how much space will it take?
What are the safety needs?
When purchasing a photovoltaic (PV) system, you should find out the maximum generating ability of the PV system per square foot. This is because the PV modules generate electricity at different rates. Given the fact that the amount of energy generated is dependent on the amount of sunlight available - which changes by season, location and time to time- the projected yield is usually within the range of 20% accuracy.
PV systems from time to time require maintenance, as does every other electrical or mechanical device. Regular, routine maintenance will help the long-term efficiency of the system and can help you reduce downtime as preventive maintenance can be carried out even before the system malfunctions.
Most of the routine maintenance tasks and inspections are things you can do yourself and if you are not the hands-on kind of person, you can contract a technician to come check the system for you periodically.
Determining the Size
In PV systems, most times size does matter. For you to get the required output that you need to run your appliances, there is a need for you to size the components of your PV system accurately. And if your need changes over time, you can easily add another energy collector panel to your PV system to increase the yield.
Apart from your electricity needs, there are other factors that determine the size of the system you need to build. These are;
System’s tilt and orientation
Energy collector efficiency
Availability of other electricity sources
Siting Of The Photovoltaic System
As it has been stated earlier, the tilt and orientation of your collector panels will have a direct effect on the output you get from your solar electric system. So you need to ensure that the tilt and orientation are just right for the specific location that you are at.
When orienting your PV modules, you should ensure that they are oriented geographically to get the maximum amount of solar energy they can receive. For the northern hemisphere, the optimal orientation is true south.
If your panels will be sited on the roof, you also need to factor in the orientation of the roof, the slant and the physical condition of the roof.
Most PV modules installed on roofs have the tilt of the roof as they are installed flat on it. The optimal tilt for the modules at an angle that’s the same as the latitude, but fixing them flat on a roof that is angled is not a problem, except the roof is pitched at an angle that is way less than the latitude. In that case, the roof angle needs to be factored in when calculating the size of the system.
