Yes, we are Tesla Certified Installers, a designation we've held since our launch in 2021. Our team’s expertise ensures that your Powerwall installation is done to the highest standards.

Typically, solar and battery installations fall under permitted development rights and don’t require planning permission. However, if you live in a conservation area or a listed building, we recommend consulting your local council before requesting a quote.

Given the Powerwall’s high capacity, a G99 application to connect to the grid is likely required, with SSEN deciding the allowable export limit. We will handle this application on your behalf, making the process seamless.

The Tesla Powerwall 3 offers a warranty dependent on internet connectivity. A consistent internet connection for remote firmware upgrades is necessary for the full 10-year warranty. If the connection is interrupted long-term, the warranty may be limited to 4 years. Full warranty details are available in the Tesla Powerwall Warranty document on Tesla’s support website.

During our site visit, we’ll advise on the ideal location for installation. The Powerwall’s advanced heating and cooling system allows it to be installed indoors or outdoors, even performing at temperatures as low as -20°C. For perspective, it uses less energy in Heat Mode than a computer monitor would for three hours.

Yes! The Powerwall can be moved to a new property without impacting its warranty, and we are happy to assist with the relocation process.

Absolutely. The Powerwall 3 includes a built-in solar inverter with a 20 kW capacity and can integrate with your existing solar setup or even replace your current inverter if needed.

Yes, the Powerwall 3 can be installed as an AC-coupled battery, meaning it doesn’t require solar. Many customers take advantage of off-peak electricity tariffs to charge the Powerwall at lower rates and use it when prices are higher, maximizing cost savings.

Yes, the Powerwall offers a reliable backup option capable of powering your entire home during outages. This feature isn’t standard in our installations but can be added at an additional cost.

Powerwall installations includes an app for easy system monitoring and control. You can view status updates, set up smart charging tariffs, and track usage. If you need help with setup, we can assist remotely.

We provide a 2-year workmanship warranty on all our installations, as required by the RECC. This covers any installation-related issues, though we maintain high standards to ensure peace of mind.

Installing a Tesla Powerwall can take as little as one day, though the duration varies based on cable complexity and the condition of the property’s electrical setup.

We are fully MCS accredited through our certification body, NICEIC, and proud members of the Renewable Energy Consumer Code (RECC). This ensures you are fully protected as a consumer and guarantees our commitment to high customer satisfaction. At CalTech Energy, we specialise in Solar PV and battery installations because renewable energy is our passion. Be sure to check out our reviews to see the quality of our work!

Ideally, your roof should face south, east, or west for maximum sunlight exposure and have enough space free from obstructions like chimneys or skylights. The roof should be in good condition and structurally sound, with minimal shading from nearby trees or buildings. If you live in a conservation area or a listed building, you may need to consult your local council about restrictions. For properties where the roof isn’t suitable, ground-mounted panels are an excellent alternative. Solar panels are particularly beneficial for properties with moderate to high energy usage, especially during the day.

In most cases, planning permission isn’t required. Solar panels are considered a permitted development right in Scotland. However, if your property is in a conservation area or is a listed building, you may need to consult your local council. For ground-mounted systems, planning permission might be required, but we offer solutions to avoid this where possible. If you’re unsure, it’s always best to consult your local council, such as Highland Council.

Installing solar panels can reduce your electricity bills by 40% to 70%, depending on factors like your location, energy consumption, and the size of the system. These savings depend on how much of the generated solar energy you use directly and the rates at which you can sell excess energy back to the grid through the Smart Export Guarantee (SEG). We provide tailored financial calculations for every design, helping you understand your potential savings.

There are no restrictions on the number of solar panels you can have, but if the inverters output size exceeds 3.6 kW (16A), a G99 application to the DNO is likely required. We often oversize panels relative to the inverter to account for lower winter outputs. If a G99 application is needed, we handle the process for you to make it hassle-free.

We use high-quality N-Type panels, which typically come with a 30-year Power Output Guarantee. This ensures that your panels will still operate at 80% of their installed capacity after 30 years. Equipment warranties are clearly outlined in your quotation. While maintenance requirements vary depending on the installation and location, it’s essential to keep your panels clean and free from debris for optimal performance. We offer maintenance solutions and include detailed guidance in your handover pack.

A typical domestic installation takes 1-3 days to complete. Scaffolding is erected a few days before installation, after which we carry out the roof and electrical work with minimal disruption. Once the installation is complete, we arrange for prompt removal of the scaffolding. After a couple of days for the system to initialise, we’ll return to ensure you’re happy with the installation and provide guidance on operating the system, including apps and settings.

Solar panels generate clean, renewable energy, significantly reducing your reliance on fossil fuels. They produce no greenhouse gas emissions during operation and can offset 1.5 to 2 tonnes of carbon dioxide annually, depending on your location and energy usage. Over their lifespan, solar panels contribute to a substantial reduction in carbon footprint, supporting a sustainable future and helping combat climate change.

Yes! It’s often more cost-effective to install solar panels and batteries simultaneously, but batteries can also be added later. Batteries store excess electricity generated during the day, allowing you to use solar power in the evening or during cloudy periods. This combination enhances energy independence, reduces reliance on the grid, and protects against rising energy costs.

There are several incentives available to make solar panel installations more affordable. The UK government offers a 0% VAT rate on energy-saving materials, including solar PV and battery storage, until March 2027. The Smart Export Guarantee (SEG) pays homeowners for excess electricity exported to the grid. In Scotland, the Home Energy Scotland Grant and Loan Scheme provides financial support for renewable energy systems.
