Rooftop vs. Ground Mount Residential Solar Comparison

In this article we will be discussing the main differences and possibilities of rooftop and ground mounted solar in residential installations. There are a number of variables that are in play in either scenario, and being educated on differences and possible issues you can

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.

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.

Hanwha Q CELLS Files Patent Infringement Complaint with U.S. International Trade Commission Against JinkoSolar, LONGi Solar, and REC Group

The ITC complaint alleges that JinkoSolar, LONGi Solar, and REC Group are unlawfully importing and selling solar cells and modules that infringe Hanwha Q CELLS's patented passivation technology.

PV System Installation Tips and Training

Railless systems can sometimes save on logistics costs, come fully assembled, and go up to the roof quickly. Generally, these systems shine at low to moderate roof slopes, snow-loads and wind speeds.

Frost Heave and Solar Arrays

For continuous racks, the vertical deformation results in additional stresses on the racking system and can cause a variety of issues such as cracked modules; solar panel distortion; damage to conductor; connection failures; and more.

Designing PV Systems with Energy Storage

For the third installment in our Solar + Storage series, we'd like to highlight a recent webinar hosted by ATA Insights about designing PV systems with energy storage in the Americas.

SEIA Releases New Go-To Guide for Residential Installations

The white paper, developed by members of SEIAs Solar Quality Assurance Working Group, provides recommended best practices on everything from contractor qualifications to the design and actual installation of a solar photovoltaic (PV) system.

Solar Industry Unveils Campaign to Streamline Solar Permitting

With the support of industry leaders, the Solar Energy Industries Association (SEIA) and The Solar Foundation today are unveiling the Solar Automated Permit Processing (SolarAPP) initiative, which will streamline permitting and slash the cost of solar installations.

California startup HahaSmart aims to become low-cost disruptor in solar

The first solar O-2-O platform (hahasmart.com) enables lower solar costs for homeowners and more business for small solar contractors

Metal Roofing Makes Solar a More Cost-Effective Residential Option

Installing a solar system on metal will increase the modules performance and decrease energy and installation costs as compared to other common roofing materials. Plus, metal also has other environmental benefits

A Guide to Safely Installing Solar Panel Arrays to Any Property Type

As the world continues to shift towards alternative energy sources, solar power will only continue to grow. Technologies will come and go and the astute product providers will continue to innovate.

DuPont Microcircuit Materials Introduces New Solamet PV76x Photovoltaic Metallization Pastes

Enabling High-efficiency Passivated Emitter Rear Contact (PERC) Solar Cells

Optimizing Solar Plant Implementation

In this paper, we will focus on a theoretical study and its application to a concrete site. We will try to answer the question: How can we optimize the implementation of horizontal trackers on a solar plant?

One With The Roof

Installers working on a tile roof must deal with particularly difficult challenges. Tile roofs are manufactured from many types of materials, including clay, zinc coated aluminum, concrete, wood and fiberglass, all of which come in a wide range of shapes and sizes. Installing solar panels on a tile roof takes more time than traditional asphalt shingle roofs and often requires additional framing.
