Winning Solar Installation Team

Never Underestimate the Value of a Winning Team! – In the world of Commercial and Industrial solar installations, putting the right team together can lead to savings of thousands of dollars in short term costs and even more in total ownership costs. When EPCs and General Contractors get the right subcontractors:

 

  • The project goes smoothly,
  • It stays on schedule,
  • Change orders are minimized,
  • Most importantly, you get a high quality installation that will withstand the test of time.

Sunstall Recognized for Providing Jobs and Clean Energy in California and in other states

The Solar Power World Top 500 Solar Contractors List includes Novato-based solar firm, which employs 28  professionals

Novato, CA—Solar power is a booming business worldwide, but local installer Sunstall Inc. is among the companies recently named to an annual and well-recognized list of North America’s top solar contractors. Sunstall Inc. achieved a rank of 38 out of 500 solar companies.

The Top 500 Solar Contractors List is developed by Solar Power World magazine to recognize the work completed by solar contractors across the U.S. and Canada. The companies on the list are growing the economy, providing jobs and offering electricity consumers a choice about how they get their power. The list was released July 26. Read more

10 Things to improve a Solar Ground-Mount Project

As photovoltaic (PV) projects have evolved over time, the industry has focused on reducing costs to increase the adoption of solar power. This reduction has been dramatic, and the corresponding increase in solar PV projects is exciting, with new records in project size and overall deployments announced nearly every year. As solar project costs drop so, too, have racking costs through the utilization of improved engineering analysis, appropriate and efficient material selection, and improved manufacturing approaches. Knowing that racking continues to play an integral role in solar installations, savvy project integrators are paying more attention than ever to products and solutions available to reduce costs and create job site efficiencies. To help end-users optimize PV installations, the following breaks down the project development and construction process, from start to finish.

Cost Reduction, State of the Art and Trends of Structural Solar BoS

From the perspective of an installer the better the planning and the better the execution matches the planning the better the end result and the less likely it is that CO’s will be issued! Sounds easy – should be easy, but in reality….. it is not that easy!

If a project is executed on the fly – the costs have to be higher than well planned & executed projects so therefore the contingency has to be higher!

Check out the presentation to get some ideas how to reduce costs & call us to discuss and support your project!

Foundations for Ground Mounted Solar Installations

Ground-mounted systems are probably the simplest way to install solar on a larger scale compared to other types of installations such as roofs or parking structures. These systems can be held down by a variety of foundations, including concrete footings, pile driven posts, piers, metal earth screws or with ballasted holding trays.

One size fits all ?

Foundation systems need to correspond to the existing site considerations and soil  static conditions according to engineering calculations and  building codes. The one size fits all approach will not lead to the most cost and resource efficient results. Here are some key factors that will help to determine the foundation type:

  • Tilt angle and tracking characteristics of the solar power system.
  • Local design wind speeds and snow loads (If applicable) where the solar power system is to be installed.
  • Support and racking configuration.
  • Overall solar module system size and weight.
  • Local design codes and project requirements.
  • Soil characteristics relative to friction, sliding, consolidation, slope stability, salinity, etc.
  • Brownfield or landfill
