At Clear Power Solutions Inc, we'd like to take a moment to showcase some of our work. You can learn more about the past work we've done below. When you're ready to get started, or if you still have any questions, just contact us today.
4.9 KW Grid-Tie Solar Array and Enerworks Two Collector Hot Water System (Rothesay)
For this project we installed 21 Sharp 235 watt solar panels, 21 Enphase M215 micro inverters, a Power House mounting system, and an Enerworks two collector hot water system. The 4.935 KW solar photovoltaic system has wireless monitoring for each solar panel. The owner and the installer can view the system performance on the internet. The system provides power to the main electrical panel in the house. From there it will go throughout the house when needed, and any excess power will feed back into the electrical grid. This is called 'Net Metering.'
This is a great picture of the Power House mounting system, the Enphase M215 micro inverters, and the solar array grounding/bonding. Each solar panel will have a micro-inverter, and the inverter is connected in phase through a main trunk cable and wired into the electrical panel. Each circuit can have 17 solar panels
8KW Grid Tie Solar with 38.4KW of Battery Backup Storage and 17.6KW Inverter/Charger System
For this project, we installed an 8KW solar array using (32) 250-watt solar panels and (32) Enphase M215 micro inverters. The system is designed to offset power consumption from the utility and also provide solar/battery backup during power outages. During a power outage this system will run the fridge, freezer, water pump, lights, mini split heat pump, and other smaller 120/240 VAC loads from the 8 KW solar array and 38.4 KW (800A/H 48VDC) battery bank. There is also a 25 KW propane generator for backup battery charging during extended power outages if it is cloudy for consecutive days.
A solar array with no battery backup has to shut down when the power goes out. This is a safety/code requirement because a system cannot back-feed the grid when linesmen are trying to make repairs to the power lines. The solar and battery system is wired in a way that it creates a micro-grid during power outages and the power cannot go back to the grid. This is called AC coupling. You can learn more by reading the Magnum AC coupling document.
Solar and battery backup systems are not designed to run 100% of the house during a power outage. These systems are designed to run critical loads like water, lights, and fridge/freezer. To run heavy heating loads like baseboard heaters, hot water tanks, and electric stoves would require a very large battery bank, inverter, and solar array. It would not make financial sense to invest in a system this large. There are a couple nice advantages to our solar/battery backup systems.
They save you money from day one. A generator is only required during a power outage. The solar array is a working asset on your house, producing power every day, which saves you money. You can recharge the batteries during a sunny day, even during a long power outage. And, there is no need to refuel the generator. The system is fully automatic and requires no maintenance. You won’t have to “hope” the generator works during a power outage — it will be there for you!
Off-Grid System That Included 2.1 KW Solar Array, 8.8 KW Inverter/Charger and 48 VDC 470 A/H Battery Bank (Kingston Peninsula)
For this project we installed 9 Hanwha 235 watt solar panels, Fast Rack mounting, a Magnum 8.8 KW inverter/charger package, an OutBack FM60 charge controller and a 48 VDC 470 A/H deep cycle battery bank. The system is designed to provide 120/240 VAC to the off-grid seasonal home.
The inverter/charger system is designed to feed 120/240 VAC to a main electrical panel. The Magnum package includes all AC/DC terminal blocks, AC/DC breakers and disconnects and a router that is used to program the inverter/charger units and displays system information. The inverter/chargers will also charge a battery bank and transfer power to an electrical panel when a generator is wired into the system. When using an auto generator start accessory, the system can be fully automatic.
