What is Solar PV?
Solar PV (Photo Voltaic) panels convert light into electricity. They work even on cloudy days, although their output is higher with brighter light. See here for our guide.
How do solar PV systems work?
Solar PV systems consist of solar panels which convert daylight into direct current DC electricity. The electricity is then passed through an inverter and connected to your fuse board to power your home.
What does an inverter do?
Inverters convert the DC electricity the solar panels create into AC electricity that your home and the grid use. The placement and type of inverter are crucial for the efficiency of the system.
How much electricity will my PV panels generate?
This depends on several factors including location, roof orientation, and system size. A typical 4kWp system in Scotland should generate around 3600kWh per year.
What happens when there’s not enough daylight to fully power my home?
Your system will draw power from the grid when there isn’t enough sunlight. If you have battery storage, electricity will be pulled from the battery to keep you running on solar energy.
What happens if my PV Solar Panels are producing more than I’m using?
The excess energy will be automatically sold to the grid when you set up an export tariff with your energy provider. Choosing a supplier that pays the most can dramatically reduce your return on investment time.
How do I know I’m using the power from the PV panels?
Your inverter will ensure that the power from your panels is used first before drawing from the grid, any good brand will have an application where you can monitor your system performance to see exactly how much you are using and saving. Most applications can be installed on smartphones, iPads, and laptops.
Do solar panels need much maintenance?
Solar panels require minimal maintenance, mostly cleaning and inspection to ensure optimal function.
How long do solar panels last?
High-quality solar panels can last 25 to 35 years, with only a small decrease in efficiency.
What are the financial and environmental benefits of solar energy?
Financially, solar energy significantly reduces your electricity bills and protects against rising energy rates. Environmentally, it reduces greenhouse gas emissions and air pollutants.
What size solar energy system should I get?
The size depends on your electricity usage and roof space. A professional assessment is recommended for an accurate system size.
What are my solar financing options?
Options include buying outright, loans, or finance. If you are interested in an air-source heat pump, additional funding options are available. Speak to a consultant for local information.
How long will it take before I see a return on my investment?
The payback period varies but typically ranges from 5 to 10 years, depending on system cost, energy usage, and local sun exposure.
Do solar panels work on cloudy days?
Yes, solar panels can still generate electricity on cloudy days, the solar panels activate at low levels of light but produce more electricity when it is sunnier.
How does battery storage work?
Store energy when it’s cheapest or greenest, using it during peak times or when the grid is down. This system includes taking charge of renewables or low-cost, off-peak grid power.
What components are used in the battery storage system?
It comprises a home battery for energy storage, an inverter to convert energy, and software for managing usage. Optional accessories include EV chargers and smart plugs.
What are the benefits of home battery storage?
Enjoy significant energy bill reductions, enhanced energy independence, and reduced carbon emissions. Smartly manage energy consumption and storage for optimal cost-effectiveness.
Can I add domestic battery storage to an existing solar array?
Absolutely. It pairs well with existing solar installations, allowing you to store and use your solar power even more effectively.
What if I don’t have a renewable energy supply?
Battery storage still offers benefits by enabling you to use electricity stored during off-peak times, reducing costs and reliance on the grid.
Is my home suitable for domestic battery storage?
Most homes can accommodate battery storage, with various sizes and capacities available to fit your specific energy needs.
What battery capacity do I need?
Depends on your energy usage, home size, and personal preferences. A professional assessment can determine the optimal capacity for your situation.
How are storage batteries fitted?
An approved installer will fit the battery in an ideal location, ensuring it is mounted safely and connected to your energy system.
Will I need to manage my domestic battery storage solution?
Systems are mostly automated for ease but offer customization options through apps or software for those who prefer a hands-on approach.
How long will my home battery last?
High-quality batteries are designed to last for over a decade, ensuring a long period of efficient energy storage and peace of mind.
