A recent study shows that solar PV panels coupled with lead-acid batteries can strongly increase electricity self-sufficiency
Nowadays, more and more people use solar PV panels and energy storage systems at home to support household electricity use. This is in line with other efforts (e.g., wind energy, electric cars, etc.) to protect the environment and achieve sustainable development. It is expected that in the near future, houses will be self-sufficient and can …

You could make a majority of your household run solely off the dc. Especially if you have a 12v system like in cars. Most energy efficient led lighting works best at 12v and you could have car-type/usb outlets around the home to plug in chargers etc. For an installation as small as a single household, you would be able to create a much cheaper system without the losses in energy to invert them to AC (then if you have transformers for your lights or device chargers, to convert them AGAIN to DC).

This would greatly improve the efficiency of the system. You wouldn't even need to adapt the original wiring for the lighting. Just move the supply cable to a DC fuse box and replace any dimmable switchgear and light fittings (the 12v spots can be connected direct instead of transformed down).

#SolarPV Poised to Boom in #Africa Thanks to Declining Costs #SolarEnergy

The business case for solar photovoltaics (PV) in Africa is stronger than ever thanks to rapidly declining technology costs, according to a new report released today by the International Renewable Energy Agency (IRENA). Solar PV in Africa: Costs and Markets, estimates that installed costs for power generated by utility-scale solar PV projects in Africa have decreased as much as 61 per cent since 2012. Today, installed costs for these projects are as low as USD 1.30 per watt in Africa, compared to the global average of USD 1.80 per watt.

Mini-grids utilising solar PV and off-grid solar home systems also provide higher quality energy services at the same or lower costs than the alternatives, finds the report. Stand-alone solar PV mini-grids have installed costs in Africa as low as USD 1.90 per watt for systems larger than 200 kW. Solar home systems – which have tripled in Africa between 2010 and 2014 – provide the annual electricity needs of off-grid households for as little as USD 56 per year, less than what they currently pay for poor quality energy services.

Materials absorbing photons and being ionized such that electrons are released are known to have a photoelectric effect, often called solar cells. When the free electrons released are captured an electric current results.

Accelerating access to #Electricity in #Africa with Off-Grid #SolarEnergy

This paper describes how the household solar market in sub-Saharan Africa has grown to date, its current status and possible future trends. The paper, one of three background papers prepared for the Energy Africa campaign launched in October 2015, seeks to understand how universal access to electricity in the region could be achieved through solar household systems. Universal access in this context means every person having access to at least one basic, entry-level solar light. The paper draws on recent studies, as well as a series of stakeholder interviews, to identify the key drivers, barriers and opportunities to accelerate market growth. These studies include those by Lighting Africa (2010, 2012), Lighting Global (2015) and GOGLA/Kearney (2014). The timing of the study meant that only some of the most recent market data, from Lighting Global/GOGLA, could be taken into account. The market for solar household solutions embraces a variety of products and services. This report considers the full range of solar devices, using terms such as ‘solar household solutions’ or ‘solar off-grid options’, except where it specifically refers to solar lanterns or larger solar home systems (SHS). The availability of information about the market for different categories of product is uneven, and the studies reviewed focus on the market for quality-certified products. While estimates of the total market for pico-solar lights are available, information about quality-certified PSLs is more robust. For the uncertified market and larger solar home systems, market information is patchy. Smaller solar lights have by far the largest share of the market, however, in terms of numbers of units. This assessment of the market therefore focuses on quality-certified PSLs.

Design of #SolarEnergy system in #FoodManufacturing environment #PowerManagement #SolarRooftop

Author: John P.T. Mo

Publisher: Cogent Engineering

Global climate change has driven many manufacturing organizations to consider renewable energy as an alternative source of power for their operations. However, the instability and unpredictability of renewable energy has made it difficult to design an optimal solution. This is particularly critical for food manufacturing which is constrained by timing and seasonable fluctuations. This paper describes a feasibility study of offsetting grid supplied power by local generation using a roof top photovoltaic system. The study shows that the company can significantly reduce their carbon emitting energy usage by a 100 kW photovoltaic solar system that helps to reduce the annual electricity consumption by 39%. The system sizing methodology has taken into account the load profile of the food manufacturing plant and seasonal solar energy availability with the constrain to consume all solar power immediately.

In principle they have to connect to the grid and have battery storage for this to work.

solar roof
 
Elon will unveil unveil a solar roof with an integrated battery and a Tesla charger :)

See why (eco+public health+etc reasons) i installed solar panels equivalent to planting 322 treesgoo.gl/JK9P9v
and why i drive an electric car equivalent to planting 382 trees (if the oil car would be refilled weekly) ► goo.gl/SnBynj.
If your panels produce more electricity than you use, you get free charging for your car too, like me. :)
Need a new roof? Why not one that can generate energy?

The US Air Force is getting into the mobile solar plus energy storage game, and taking it into battle. The idea is to scavenge renewable energy at forward operating bases instead of relying on diesel fuel shipments. Aside from relieving FOBs from the burden of fuel delivery risks, the solar plus storage equation allows for
