We’ve compiled a list of our most commonly asked questions around solar power. We aim to provide non biased answers that focus on the homeowner’s best interests when selecting solar equipment and a solar installation provider.
Energy from the sun is transferred by the panels into DC power by small photovoltaic cells. The DC power is then converted to AC power and connected to an energy source, such as your electrical panel. There are two main types of solar installations: grid tied and off-grid.
Solar installations in Nova Scotia typically result in a 10% annual rate of return or more. It’s a great financial investment as well as an investment for the future of our planet.
We are always happy to provide a free quote. Every system is different and designed to your budget and needs. To accurately compare quotes, the total system cost should be viewed as the price per watt DC after HST and rebates applied (including any additional costs).
There are a lot of factors which determine how many solar panels you will need. Roof or ground space, pitch, roof material, orientation of system, shadowing or obstructions and historical electrical usage. For instance, if you use 10,000 kWh in a year, then your solar system cannot produce more than 10,000 kWh in a year. Most homes average between 18-30 solar panels to achieve net zero. We design each system to match your budget and requirements.

A grid tied system relies on power coming in from the grid in order to produce electricity. If there is a power outage, a grid-tied solar system will not work without a backup (battery, etc) system in place. If you’re interested in this option we can offer a solution for various types of backup power. Please contact us for more information.
We are located in Dartmouth, NS and are 100% local to Nova Scotia. We started our business here in 2013 and have 100% local ownership as well. We also have a US branch based in Austin, TX.
We currently install solar anywhere in the province of Nova Scotia.
We only install products with a full 25 year warranty including: solar panels, racking and micro-inverters. We offer a 5 year workmanship warranty on any installation.
Any solar panel which has a Tier 1 rating is a safe bet. Tier 1 status means the panel manufacturer is in good standing, with large financial backing and quality assurance on their product. It is also important to consider efficiency, degradation, and warranty of the panels. A balance of quality, performance and price is the key in selecting a great panel. We only install panels with a 25 year warranty which are Tier 1.
Currently, in Nova Scotia, if you have a grid-tied solar system then your regular power meter will be changed with a bi-directional meter. The meter will spin backwards and count excess power produced from your solar system. This shows up as a credit on your power bill. Your power bill then has a charge for usage and a credit for solar production. The difference will carry over to the next power bill. Once a year, a “true up” period happens where any unused credit can be issued as a cheque from NSPI to the homeowner. To learn more, visit Nova Scotia Power’s website about Enhanced Net Metering.
All solar companies will need your power bill to see your historical usage in order to design a system appropriately. The Enhanced Net Metering Program only allows a system to be up to 100% of your historical usage (total kWh for the year).
This is one of the most important yet overlooked parts of a solar system. When considering the long term life of your roof, we want to be confident that the product used is well tested and water tight. A product should not rely on guesswork during installation (like locating the centre of a roof truss). That’s why we currently use either a Talon or RT-mini for attachments to an asphalt roof or corruslide or S-5 clamps for a metal roof. Also, we would never recommend using PVC strapping directly on a roof when installing electrical cable runs. By doing so, you are introducing new areas for water to enter over the lifetime of your installation and is not best practice in the industry.
We generally recommend replacing your roof shingles if they are over 10 years before installing a new solar system. The solar system is warrantied for 25 years so it is best to have the roof and and solar system’s life span line up to avoid added costs of removal of panels to replace shingles. However, by adding solar panels over your roof, it adds a layer of UV protection and will increase your roof’s life expectancy.
The short answer is no. It can be very dangerous to run two competing generating sources on the same circuit. It is important to isolate your solar system when running a generator either through a manual switch or ATS (automatic transfer switch).
No. Many insurance companies understand solar and in some cases little to no annual increases are added to your overall premium.
