As the world transitions towards cleaner and more sustainable energy sources, solar panels have become a popular choice for home and business owners.
At AW Electrics we understand you may have several questions about solar energy and solar panels; this article addresses some FAQs that we hope will aid you to make more informed decisions.
Below are the answers for 8 FAQs, we are most often asked.
Yes! Contrary to popular belief, solar panels can still generate electricity even in cloudy weather. While direct sunlight produces the highest electricity output, solar panels can still generate a significant amount of power on overcast days.
Yes! Solar panels work based on the amount of daylight rather than heat, meaning they can produce electricity even in cooler temperatures.
No. While a south-facing roof is not absolutely necessary for installing solar panels, it is generally considered the most ideal orientation for maximising solar energy production.
South-facing roofs receive the most sunlight throughout the day which allows solar panels to capture the maximum amount of solar radiation.
However, solar panels can still be installed on roofs facing other directions and can generate a significant amount of electricity.
Panels facing east or west perform at around 86% compared to south facing.
The exact impact will depend on factors such as the angle of the roof, shading from nearby objects, and the specific solar panel technology used.
To determine the feasibility of installing solar panels on a non-south-facing roof, it is advisable to consult with a solar energy professional or installer who can assess your specific situation and provide accurate recommendations.
No. Solar panels require sunlight to convert into usable energy. They generate the highest amount of electricity around midday when the sun is at its highest point in the sky.
During nighttime, solar panels do not generate electricity because there is no sunlight available.
To have a supply of electricity during the night, solar panels need to be combined with energy storage systems such as batteries.
These batteries can store excess electricity generated during the day and release it during nighttime or when there is less sunlight available.
By integrating storage systems, it is possible to have a more reliable supply of electricity from solar panels and reduce your reliance on the grid.
The typical recommendation is at least an 8-panel Solar PV system, which can conveniently fit on the roof of an average 3-bedroom semi-detached house.
However, some panels produce a greater amount of energy per square meter and other panel varieties, allowing you to generate ample electricity even with a smaller roof space.
Solar panels are designed to be durable and long-lasting.
They contain no moving parts apart from the inverter, which reduces the likelihood of mechanical failure or wear and tear.
The inverter should last around 10 years and is replaceable.
The average lifespan of solar panels is around 25 to 30 years, although many systems continue to operate efficiently beyond that timeframe.
Additionally, most solar panel manufacturers provide warranties of 20 years or more, ensuring the performance and durability of the panels.
Solar panels are relatively low maintenance.
Occasional cleaning to remove dust, debris, or bird droppings is recommended to optimise their performance.
Window cleaning companies often have the correct equipment to clean your panels for you.
Solar panels are designed to be weather-resistant, so they can withstand rain and snow.
It is advised to have a professional inspection every few years to ensure the system is functioning optimally.
Your inverter will switch off if there is a power cut.
This safety feature ensures that the panels do not continue to generate electricity that could potentially harm utility workers trying to restore power.
However, it is possible to have a backup power system in place by incorporating a battery storage system into the solar panel setup.
The excess electricity generated by the solar panels can be stored in the batteries, which can then be used to power essential appliances or the entire home when the grid is down.
