In 2004, the average price of an installed rooftop solar module was about US$3.50 per watt. The cost of solar in the USA is now plummeting. In the four years since 2016, solar modules prices have (in all USA markets) fallen from US$ 0.63 per watt to about $US 0.20 per watt.
Battery charging quickly and deeply by a generator is very possible but only if you know how it has to be done. This article shows why and how.
Upgrading an existing solar system has unexpected traps. It is often better to scrap, use elsewhere, or attempt to sell that existing, and install a new one. This is particularly so with grid-connect systems and doing so with stand-alone systems is still tricky.
Charging your electric car at home Charging your electric car at home or workplace is readily feasible. Most electric vehicles have a charging unit inbuilt. Check with the vehicle maker for charging options available. This article about charging your electric car at...
The market for quickly-rechargeable, light and compact batteries is huge. One or another battery will eventually evolve. When it does, electric-only vehicles are likely to have a range unthinkable using fossil-fuels. Moreover, in the meantime, hybrids are an excellent compromise. Furthermore, see also Electric Vehicles – Hybrids.
Many existing home grid-connect solar systems have excess capacity outside peak periods. Solar energy fed in during the day can be re-drawn during off-peak periods, for much the same price, to charge an electric car. This is because many grid networks have excess capacity outside peak periods. Furthermore, such charging extends battery life: all dislike ongoing deep discharges.
Updated 2020 Electric vehicle history Electric vehicles have existed for longer than most people think. They long pre-date petrol and diesel. This electric vehicle history by Collyn Rivers is an overview. The first dc electric motor (1866). Pic: Siemens UK. The...
Updated 2020 Electric vehicle motors AC/DC Electric vehicle motors use one or other of the two main kinds of electricity: alternating current and direct current. Both are effective as electric vehicle motors. Alternating Current (AC) is where electric current...
Updated 2020 Electric Vehicle Efficiency & Emissions This article, by Collyn Rivers, discusses electric vehicle efficiency and emissions. All road vehicles emit pollution (and are health issues). Emissions are in two main forms. One includes haze and particulate...
Electric-only vehicles of today are most suited to urban driving, but as battery technology inevitably advances, and charging facilities increase, these will be decreasing issues.
Updated 2020 Electric vehicle hybrids Electric vehicle hybrids are powered by either or both electricity and fossil fuel. They are far from new. In 1898, Ferdinand Porsche developed a hybrid car (the Lohner-Porsche). Its petrol engine ran a generator powering electric...
Fuel cells for homes and properties provide clean silent electricity. High current prices hinder their acceptance, but this may soon change. Fuel cells enhance solar. Furthermore, they may all but eliminate our need for battery storage. Fuel cells hugely reduce harmful emissions.
This vital easy to read guide shows you how to convert to your own all solar home at minimal cost. You can readily do this in much of the world between 50-degree latitudes north/south. This easy to read article shows that doing so can save you thousands of dollars.
It is now virtually certain that about half of all cars will be electric by 2030. The current part fossil-fuel/part electric hybrids will be phased out as battery storage technology advances (to provide comparable range) and the recharge network becomes global.
Interconnecting batteries in series or parallel is totally feasible. But its best to know how it works – and the limitations of each. Collyn Rivers explains.
Using grid connect solar modules for RVs is readily done but needs an MPPT regulator. This article by Collyn Rivers explains how and why it is done.
Globally, there is move to electric vehicles. Apart from minor rubber tyre particles they are virtually emission free.They are also about 80% efficient. If, however, their electricity is from fossil-fuelled power stations, their emissions are similar to year 2020 petrol-fuelled (or hybrid) vehicles.
It is often feasible to have portable solar in your rented home. Here’s how to do it simply, safely, legally and cheaply using readily bought parts. It requires space that faces the sun for some daylight hours year-round. It must also be within 50 degrees latitude north or south. You use high efficiency maximum-size solar modules to maximise input
We always wanted to stop paying for electricity, and now we have. It getting easier to free yourself from dependence on the grid. We decided against going off grid. Why waste excess electricity when someone is willing to pay for it!
Connecting travel trailer batteries is often misunderstood. This article explains what’s possible, and why and how to do it successfully.
