• New MPPT Charge Controllers for Canadian Solar Systems

    EPS is an innovative manufacturer who have designed solar charge controllers that work perfectly with the new value priced 60 cell solar panels like the SF-220 and SM-265MC.  This article explores the options and their advantages for Canadian cabin owners.

    10 years ago most off-grid cottages used 36 cell modules like the HES-100s.   60 cell modules needed very expensive MPPT charge controllers like the Outback FM-60s or Morningstar Tri-Star MPPT series.

  • Solar on a Strata - Two Years Now

    Note: This is another entry in the 'Solar on a Strata' blog series <https:bcsea.org/solar-on-strata It chronicles the planning, installation, and ongoing experience with a 60-module solar PV installation on Central Park Strata, a 63-unit condominium in downtown Victoria. HES-PV supplied the hardware such as Fronius Inverters and Solar Panels in June 2015. I was the Strata President and led the project to install them, and continue as a volunteer adviser to the Strata Council.

    Bottom line: There isn't much to report in the last year and a half. The system continues to produce electricity every day, without maintenance. I asked the current Strata President if they would like me to come to their next AGM to answer any questions, and her response was:

    We have asked around about the solar panels, and nobody really showed much interest in learning more about them. I think that overall, people are just happy that they will eventually pay for themselves and generate power, but that's the extent of their interest. Unfortunately, I think that by coming and doing a presentation would be a waste of your time.

  • Electric Vehicles and Solar Charging

    The EV Paradigm Shift? Electric vehicles from Big Auto first appeared 5 years ago, with the introduction of the Nissan Leaf, and the new Tesla. Now Telsa rivals GM for a spot as a top auto maker, and almost all automakers are following Nissan with 100% electric versions in their fleets. Canada had 30,000 plug in EVs sold by the end of 2016, with the growth curve looking similar to the growth of the solar installations!

    How does the transition to EVs effect the solar industry? Very positively so far. In Victoria a significant number of solar systems have been installed on home for EV buyers. Institutions are adding solar to EV charge stations to offset the new loads. And environmental consciousness is helping EV buyers account for the source of their energy.

    Although we have titled this article the future for PV, the reality is that we have being implementing PV storage systems since the beginning of our industry. The systems were being deployed in what we call the 'off-grid' market, telecom, coast guard, cottages and RV. The big change that is coming will be the amount of PV storage connected to the grid.
