Why shading technology for solar modules makes a difference
Day4 Energy’s propriety and patented technology enables its modules to produce more electricity than other solar panels in real-world applications, minimizing the impact from shading and excelling in low light conditions.
What sets Day4 Solar Panels apart from other solar panel manufacturers?
Day4 Electrode - solderless modules
The Day4 Electrode replaces the conventional PV cell soldering process that is used by other Solar Panel manufacturers. This improves power output and aesthetic appearance. The Day4 Electrode is a polymer film embedded with specially coated copper wires coated with a low-temperatue melting point alloy that is designed to establish a low-resistance electrical contact with the surface of the PV cell.
Day4 Guardian Technology - Intelligent Shade Technology for the Real World
Day4's premium solar panels have shading technology that produces more energy than other solar panels. A solar panel can lose power generation when it is shaded or partly shaded from the way the cells are connected within the solar panel. Solar cells within a solar panel are strung together in series much like Christmas lights, when one cell underperforms a whole string can fail. To prevent a whole string from failing, a typical solar panel has bypass diodes that reroute current around the underperforming cells. Rerouting the current loses not only the potential energy from the cells but also lowers the entire string's voltage.
The string of solar panels feed DC current into an inverter that converts it to AC power and optimizes the PV array's power generation through maximum power point tracking (MPPT). In the case of a shaded cell, the inverter is left in a dilemma, optimize the voltage for the underperforming string or maximize the energy harvest from the unaffected strings. In most cases the inverter does the former, causing the power production of the impaired string to drop to near zero.
Day4's Guardian Technology 'Intelligent Shade Technology for the Real World' leverages the flexible cell layout feature of the Day4 Electrode creating a large number of independently operating segments that are able to function even if one or more are shaded.
This allows exceptional performance:
- 3 times less sensitive to the effects of shade from debris
- Up to 25% higher annual energy yield from the project area
- Significant increase in annual energy yields for 1-axis horizontal tracker applications due to longer harvesting hours
- Up to 60% less mounting materials required
- Able to install on previously unsuitable sites
Better Technology = Higher Returns
PV Power Plant integrators buy PV systems based on expected returns. Day4's largest installation, owner EnBw German utility, had the following results for 2008:
Performance in low light conditions means more overall higher power production - even under snow loads
This is a 860kw solar system in Portland that was under about a foot of snow cover during the big snowfall in winter of 2008. Under this snow cover, the Day4 solar system still produced 14 kw!
Day4 solar panels use the best materials for production and provide premium power output and long lasting dependable power production. The modules have 25 year Power Warranty and a 10 year product warranty.
