Energy is a very exact and precise industry, which tends to mean there are a whole lot of very specific questions about our products and services. So here we have compiled a collection of some of the questions we get asked the most. If you can’t find an answer below, and still have questions please just get in touch directly and we’ll be happy to help.
Frequently asked questions
HOW MUCH WILL I SAVE?
Whilst there are costs to you in purchasing and owning the solar system, solar power will help you to reduce your monthly electricity spend by offsetting the energy usage in your house. How much your monthly electricity bill will reduce by will depend on a number of factors, including the size of the system that you install, how much electricity your system generates, and how much electricity you use during the day.
IS MY HOUSE SUITABLE FOR SOLAR?
If you roof is in good condition, and gets a lot of sun, it is probably a good candidate for solar. Genesis does not recommend installing solar on old roofs. The panels are expected to last for over 25 years so it is not recommended to install them on a roof that may need replacing during the life of the system.
WHAT SIZE ARE THE SOLAR PANELS?
The size of the system is often determined by the available roof space of the property and size of the system you require. As a guide, most panels are 992mm wide by 1640mm high in size. Approximately 8 m2 of roof space is required per 1 kW of solar panels.
WHAT WILL BE AFFECTED ON MY ROOF?
All the Solar PV panels are designed to be mounted on top of an existing or new roof and are not normally heavy enough to cause structural problems. However, bolts are used to secure the system to your roof and if the panels are removed, these bolts will remain.
HOW MUCH MAINTENANCE DO SOLAR ENERGY PANELS REQUIRE?
Solar photovoltaic panels require little maintenance. Your panels can build up dust and other material over time. Solar panel cleaning is not that different from cleaning your windshield. This can be done with soapy water and a soft brush.
WILL THE SOLAR PANELS STILL OPERATE IF I HAVE NO ELECTRICITY?
No, the solar panels require you to be connected to the local grid for them to operate. If power is cut to your home, the solar panels will not operate. This is a safety mechanism to protect appliances at your property and for the safety of network maintenance personnel.
DO I NEED PLANNING PERMISSION OR OTHER CONSENTS?
Solar PV systems do not need generally require planning permission unless the property is a listed historic building or in a conservation area. If your home is on a cross-leased property, you may need consents from other property owners on the cross-lease and we recommend you discuss this with your cross-lease neighbours.
WILL I NEED A BUILDING CONSENT?
Most Councils take the view that installing a solar PV system is energy work (like installing a heatpump) which means it is exempt from requiring a building consent. However, some Councils don’t. For example, we know Hamilton City Council requires a building consent, whereas Auckland Council, Tauranga City Council, Manawatu District Council, Wellington City Council, Nelson City Council, Christchurch City Council, and Dunedin City Council all allow the installation of solar PV systems without a consent. It is worth checking with your council. Heritage listed buildings or homes in heritage areas will most likely require a building consent.
