First-of-its-Kind PV Inverter Scorecard Ranks Manufacturers by Performance
Public report from PV Evolution Labs reveals over 20% of tested solar inverters failed safety and reliability tests while others had strong performance following testing.
Power Optimizers Match Infrared (IR) Imaging Capabilities at Finding Module Defects
Power optimizers have the advantage of finding and quantifying failures continuously during operation.
Can Renewables Be a Greener Alternative to Replace Fracking?
Even as fracking has reduced the cost of natural gas, improvements in renewable energy technologies have brought their costs down to be cost-competitive with fossil fuels. In many cases, they can compete even without tax incentives in place.
Renewable Energy in United States Has Exceeded Coal for the First Month Ever
The clean energy revolution of America is at a tilting point. A recent Institute for Energy Economics and Financial Analysis report stated that the renewable energy sector in United States generated more clean energy in April than power plants using coal.
Pointers for Successful Inclusion of Solar Home Systems as Power Backup Support in Rural and Small Towns of India
Enhancing access to reliable power would mean improving transmission infrastructure and electricity production capacities. Both these initiative would demand investments and a considerable timeline.
How to Design a Solar Power System
Designing a solar power system isn't as easy as just slapping a few panels on the roof and calling it a day. What do you need to take into account when designing a solar power system?
Talking Single-axis Tracker with Kevin Ward, RBI Solar
RBI's Sunflower single-axis tracker is designed and engineered to meet the project development challenges of topography and maximized PV density. The system has an articulating table design, which accommodates undulating North/South slope tolerances up +/- 10%
Solar Decathlon Design Challenge Takeaways
Being a juror is an amazing experience. It is heartening to see how thoughtful the teams were in their designs. The students included innovative approaches to achieve the design goals and some created models to show off their design.
Reusing Renewable Energy Products
We started RENewed Wind and Solar because we don't think quality renewable energy equipment should sit in a warehouse - or worse, go to a landfill. We think there's a better way. Reuse.
How to Design a Rooftop Solar System for Maximum Energy Density?
For some installations it may make sense to reduce the tilt of the modules to a less optimal incident angle. Though this means less production on a per module-basis, it can mean a significant increase in the daily unshaded collection time for the array.
Trend to Watch: Bifacial Modules
Bifacial solar modules are becoming more popular in the solar industry. These modules can absorb sunlight from both sides as opposed to just one. Therefore, they can convert the light that is reflected behind the panel to increase the total energy production.
How Civil Work Erodes Project Economics
Both on paper and in the field, civil engineering can quickly drain your project's margins. From the intricacies of installation logistics to the added costs of non-standard products, margins become slimmer as development becomes more and more complex.
California Leads Nation in Residential Solar Installation Rates, Overall Homes and Total Capacity
Gavop's analysis of latest solar installation data from SEIA and census data shows that California leads the nation at 44.92% of all homes installed with solar home. California also leads the nation with total homes installed with solar power at 6.3M total homes ...
When Augers, Ground Screws Make Economic Sense for Solar Contractors?
The use of augers and ground screws have been of interest in solar ground mount systems for some time, and for the right sized job, they offer solar contractors an opportunity to grow their business.
What Can a Solar Integrator do to Maintain and Grow Business
Whether an integrator is just trying to make it day to day or looking for ways to expand, the key is customer satisfaction. This starts with sales. There is a two-way relationship between sales and operations, which is essential to creating satisfied customers.
