Advantages of HDPV Inverters with Ampt Optimizers

The HDPV™ Alliance brings solar industry equipment manufacturers and solution providers together around a common vision for the development and adoption of lower cost and higher performance PV systems.

Solar Tracking Technology

The demand for trackers has expanded significantly in recent years as more reliable and cost-effective solutions come to market. According to a recent study by Transparency Market Research, the global installed capacity for solar trackers is estimated to reach almost 9 GW by 2020.

The Benefits of Power Optimizers

Power optimizers are a module-level power electronics (MLPE) solution that can be affixed on-site or embedded during the manufacturing process as a replacement for the junction box.

From Selenium to Silicon and Beyond

The 60th Anniversary of the First Practical Solar Cell

Unbiased, Comprehensive Solar Module Rating System

Although we have over 12, 000 PV modules in the database today, we are always searching for new modules. Manufacturers and consumers can contact us if they have modules that are not listed.

Solar PV - Now and Tomorrow

Network planning and grid control is an undeniable challenge as an increasing number of large-scale PV installations feed energy into the utility grid, but we see this shifting in the next 2-3 years.

3D Solar Modeling Technology

To assess the accuracy of simuwatt Solar, concept3D partnered with NREL to evaluate the program's outputs against actual plans developed for sites across the country.

Power on Demand

Designed for the Battlefield …Indispensable on the Construction Site

Solar Powered Unmanned Vehicles

When you have the combination of high energy density and thin and flexible form factor, you can apply this solar material to anything with a battery that moves, can be carried, or worn.

Solar Hot Water: Which is better, PV or Thermal?

Recently, reductions in solar electric (PV) costs and maturation of air-to-water heat pump technology have provided a new model: solar-electric assisted heat pump water heating (HPWH).

A Distributed Solar Utility

Unlike a traditional, large thermal power plant, where hundreds of megawatts or even gigawatts are generated in a single geographic location, our solar facilities will be distributed all across the country and eventually, around the world.

Solar Pumping Issues and Solutions in Pakistan

Solar pumps have high initial costs but almost zero operational, maintenance costs and environmental costs. Now which one is cheaper in its life time operation of 20 years?

Solar Likely on 20% of New Homes in California in 2013

CSI data shows that 4,000 new homes were built with solar in California last year. SunPower observes that that's 10 times the number built in 2006, when the housing construction market was booming.

Inverter Innovation and Overall System Cost-reduction

By differentiating between a true utility outage (where anti-islanding is necessary) and a grid disturbance (during which the PV system could actually help support grid stability), inverters can stay online during grid disturbances and produce responses to stabilize the grid.

New solar cell technology improves efficiency by 15%

Three months of experimental validation allowed us to refine the technique to the point we could pursue grant funding from the National Science Foundation (NSF) Small Business Innovation Research (SBIR) program and submit a provisional patent application.
