A yieldco is a publicly-traded company which aims to create growing dividends. More yieldcos are entering the renewable energy market, and the existing ones have grown quite fast in the last year.
RE-volv is a nonprofit organization whose mission is to empower people and communities to invest collectively in renewable energy. RE-volv finances solar energy projects for nonprofits and worker-owned cooperatives that serve their community through a 20 year solar lease agreement.
The Thin Film Solar Cell Industry In Transition: Knockout Phase Is Over - Profitability And Vertical Integration Next
The implementation of PV into buildings should not be considered an added novelty product supplementing current construction materials, but rather be seen as an integrated part of roofing and facade material that could add substantial value to building material suppliers' range.
Giannoumis has found that using PictometryOnline™, with access to high-resolution aerial imagery and analytical tools, combined with solar roof reports and CAD-compatible .dxf files provided by EagleView Technologies, is the key to maintaining productivity. This technology is also offering the company a new level of profitability and accuracy throughout the system design process.
China continued to deploy wind power at a remarkable rate, installing an estimated 23.3 GW in 2014, a 45% increase over 2013. China accounted for 45% of the 51 GW installed globally in 2014, representing $94.6 billion in revenue.
Data from AMP and Ohio State shows that wind power in Ohio is a good deal for its customers, and that its price is competitive with, and in some cases significantly cheaper than, other sources of power.
While buying a solar panel one must keep in mind various factors like where it will be installed, purpose; commercial or residential use, and budget.
The installation involved locating where the fastener is going, driving the fastener into the metal deck underneath the insulation and membrane, sliding the PowerGrip over the fastener head, and hot air welding it in place.
It is important to pay attention to product specifications regarding the rate at which energy is coming in, the amount of energy stored, and the rate at which that energy is being consumed.
Adopting a building-integrated solar air heating system for a multi-residential, high rise exterior retrofit of the Lyndon B. Johnson public housing complex in Cambridge, Massachusetts.
The system incorporates panels and micro-inverters and steel and bearings and a microcontroller with an LCD display, to control the daily motion of the array. And, I might add, a light sensor to sense night time and daytime, and an AC current sensor to measure the amps produced (by the array) and amps consumed by the controller.
Renewable Energy Corporation, a Baltimore solar panel installer, created the graphic below to show how Maryland and Virginia measure up against each other.
1.7MW and 1.2MW installations will provide equivalent power for roughly 920 average households.
We have researchers here developing systems that should be able to convert more than 40% of the incoming sunlight to electricity (current panels are ~20% efficient). We are also working with research groups that can generate fuels and chemicals directly form sunlight, or from biomass, hopefully at an efficiency and cost that will replace conventional fossil fuel materials.
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.

Joyce Solar Actuators are designed to precisely position smaller solar tracking equipment. Their robust and efficient DC motor (24V or 36V) keeps power consumption to a minimum. Travel speeds remain nearly constant regardless of the load. Ideal for rugged environments common to the solar industry, these cost-effective SA actuators have an IP65 protection rating. Self-locking features in the mechanism ensure that the solar actuator will hold position throughout the daily tracking cycle. Specifications: • Double clevis mounting for easy installation • Clutch for overload protection • Adjustable limit switches for flexible travel settings • Reed sensor digital feedback for accurate positioning • Duty cycle is 25% (4 min. running, 12 min. rest) • Lubricated for life
