Alternative Energy White Papers

In this White Paper, the BiTEC analysis center places special emphasis on the importance of albedo to achieve more satisfactory results in obtaining energy. In this way, we conclude that the lighter colors of the soil and a softer texture result in a higher albedo and a greater generation of energy in bifacial modules.

This whitepaper is the second part of a summary presenting the results obtained from November 2018 until March 2019 at Soltec’s Bifacial Tracker Evaluation Center (BiTEC) in Livermore, CA, USA. BiTEC studied Bifacial Gain in photovoltaic modules developed according to the two most common tracker market configurations nowadays: one-in-portrait (1P) and two-in-portrait (2P). Results obtained during fall and winter months show that individual modules in two-in-portrait configuration trackers obtain a Bifacial Gain of 16.8% under high albedo conditions (59.6%), which is 2.2% more than the same modules under a 1P configuration trackers for identical conditions.

Rooftop solar has come a long way over the past decade. The ever-improving quality of equipment and components, enhanced level of expertise, consumer-friendly financing and huge price drops have all contributed mightily to turning residential and commercial/industrial solar into a thriving multibillion-dollar construction/energy sector in the United States and other countries. As the industry grows and more contractors get into the solar business, we know how important it is to provide useful tips and solid information on installation best practices from the mounting perspective—especially those that help installers keep their operations lean, the quality of their work high, and their businesses profitable.

This program is one of the most thorough of its kind, guided by a multistep inspection protocol at sites in North America, Europe, Asia, and the Middle East and staffed with some of the most experienced scientists in the solar industry. This team of experts has compiled global data from 6.5M modules, 355 Installations and 1.8GW of Total Power

Learn how to save on energy costs by optimizing your facility flows that impact costs like compressed air, natural gas, steam, and hot or chilled water.

In recent years energy storage has emerged as a key ally for the renewables industry, allowing excess production to be stored and sold when market conditions are favorable. And while the addition of batteries to renewable projects was originally a costly exercise, a rapid fall in the price of lithium-ion battery technologies now means solar and wind plants can be equipped with significant levels of energy storage and still remain competitive.

The robust design fully supports the array weight ensuring that all loads flow from the modules down through the racking system and into the ground – without placing secondary stresses into the modules or depending on the modules to brace the system. By protecting the most important component of your solar system, the solar power modules, Solar FlexRack safeguards solar project budgets.

Environmental monitoring is critical to optimizing the efficiency of solar power generation. Beginning with site assessment, on-site meteorological monitoring factors into overall project performance and ROI. Weather stations provide reliable data on parameters such as solar radiation, wind speed and direction, temperature, and precipitation that influence location and efficiency of solar panels.

Design, equipment, fields of application: Many things have changed with quadrupole mass spectrometers (QMS) over the last 30 years. They have become more compact, durable, versatile and digital. Initially used primarily in research, QMS are nowadays utilized in the semiconductor industry, freeze-drying or leak detection, for example.

Large off-grid and battery backup PV systems, often require greater charging than a single controller can provide. To meet the charging requirements of these large systems, several TriStarâ„¢ or TriStar MPPTâ„¢ controllers can be connected in parallel to a battery bank. Each controller is connected to its own separate PV array. This document provides answers to frequently asked questions, and tips concerning the operation and setup of these large multiple TriStar and TriStar MPPT controller systems.

With so many different battery technologies on the market today, it can be difficult to make sure you’re selecting the right battery for your application. This document will describe the basic types of lead-acid batteries available, and help you understand which one will provide the best performance and value for your needs.

The white paper describes opportunities for distributed resources to provide value to the electric grid and the environment, along with program improvements that are needed to encourage customer investment.

This is a report from the Global Grid Transformation (GGT) conference track at Energy Storage North America (ESNA) 2018, which took place in early November in Pasadena, California. The event brought together key stakeholders from Australia, Europe, and the Americas to exchange ideas, share success stories, and brainstorm on key challenges, with a focus on promoting a low-emission, resilient, and affordable power grid. IHS Markit worked together with ESNA to prepare this white paper, providing a recap of the most important points faced today by the energy storage industry, including how various markets are developing and how stakeholders can identify and target growth opportunities for energy storage.

More than 90 U.S. cities and 140 large corporations have established 100% clean, carbon-free and/or renewable energy goals in recent years. California, with its new mandate that 100% of its energy power must come from non-carbon sources such as solar and wind by 2045, joins Hawaii, which previously established a similar goal. In several other states, newly seated governors campaigned in 2018 on goals of 100% renewable energy, and congressional representatives were sent to Washington positioning for a like-minded national proposal. Setting 100% clean energy or renewable goals is a significant step, but the question remains: what really has to happen to get from here to there, and what are the benefits such a transition will bring?

The frameworks in this slide deck can help those in the power sector understand and analyze key power system design criteria, different constructs for future utility business models, and evaluation criteria for the different utility business model constructs. SEPA developed a set of frameworks to help synthesize the collective insights gathered from Phase III of the 51st State Initiative

Dive into the three phases of the 51st State Initiative that initiated the creation of novel ideas for a better energy future. As a capstone to the 51st State Initiative, this paper captures the evolution of thinking through the initiative’s phases.

HiveMind sequestered 135 metric tons of CO2e in four inches of soil on a 500 square feet green roof at Cummin’s Huddersfield diesel plant. Our data from over a dozen sites in the US give an average of 100 tons CO2E sequestered per 1,000 square feet on a standard sedum roof of four inches. There are 43,560 square feet in an acre, so it’s possible to sequester 4,300 tons of CO2e over ten years on acres of land. Central Park is 840 acres so it’s possible to sequester 3.6 million tons of CO2e in a space the park’s size. That’s the carbon footprint of 180,600 Americans. We believe that’s a better solution than a park full of giant air sucking fans.

Developed by the SEIA Quality Assurance Working Group, this document was designed to update installation best practices originally developed by the Solar Access to Public Capital (SAPC) working group organized by the National Renewable Energy Laboratory, and is intended to be updated as proper protocol dictates. The primary intention of this document is to provide recommended best practices to facilitate high-quality and consistent residential solar projects. The broader objective in developing and maintaining this document is to build confidence among potential solar customers, regulators, investors, rating agencies, and other stakeholders in the concept that residential solar systems are a valuable home improvement, a consistent and long-term electric generating resource, and credit-worthy investment asset class.
