1. How do you calculate the amount of energy we can generate from a commercial solar PV array?
Answer: The amount of energy that can be generated from a commercial solar PV array can be calculated by multiplying the size of the array (measured in kW) by the number of peak sunlight hours per day for the location. This will give you the number of kilowatt-hours (kWh) generated per day.
2. How do you calculate the amount of energy we will save by installing a commercial solar PV array?
Answer: The amount of energy saved by installing a commercial solar PV array can be calculated by determining the amount of energy that the array will generate and subtracting that from the amount of energy that would have been purchased from the utility company. This will give you the amount of energy saved in kilowatt-hours (kWh) per day.
3. Should we install batteries with our commercial solar PV array?
Answer: It depends on your specific energy needs and usage patterns. Batteries can be beneficial for storing excess energy generated during the day for use at night or during periods of low sunlight. However, batteries can also be costly and may not be necessary for all commercial solar PV array installations. Our engineers can undertake detailed calculations to review the viability.
4. What is the lifespan of a commercial solar PV array?
Answer: The lifespan of a commercial solar PV array can vary depending on the quality of the panels and the overall system design. On average, most commercial solar PV arrays are expected to last for over 30 years.
5. What are the maintenance requirements for a commercial solar PV array?
Answer: The maintenance requirements for a commercial solar PV array are minimal. Most commercial solar PV arrays require only a few simple tasks, such as cleaning the panels and checking the electrical connections. Watt Energy Saver has an in house O&M team who can look after your array for you.
6. How does a commercial solar PV array connect to the grid?
Answer: A commercial solar PV array connects to the grid through an inverter, which converts the direct current (DC) electricity generated by the panels into alternating current (AC) electricity that can be used by the building and sent back to the grid.
7. How does the weather affect the performance of a commercial solar PV array?
Answer: The weather can have a significant impact on the performance of a commercial solar PV array. Cloud cover, snow, and dust can all reduce the amount of sunlight that reaches the panels, which can decrease the amount of energy generated. However, commercial solar PV arrays are designed to withstand most weather conditions and can continue to generate power even in overcast conditions.
8. Do I need planning permission?
Answer: In most circumstances, solar arrays less than 1MWP fall under Permitted Development rights. Watt Energy Saver will guide you through this process and help make a necessary applications.
9. What is a G99 application?
Answer: A G99 application is required in the UK for certain types of solar energy systems. It is a formal application to the distribution network operator (DNO) for connection to the electricity grid. Watt Energy Saver will manage this process on your behalf. This poses the greatest challenge for the connection of a Solar Array. Watt Energy Saver has over 13 years of experience in securing a grid connection for our clients, where many others have failed.
10. Can I monitor my arrays performance online?
Answer: Yes, we can install a web-based device which records and transmits data such as energy production, weather conditions and performance of the solar array. The system allows the user to track performance, identify issues to take corrective action, and also have an alerts / notifications feature.
