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.
Charging your electric car at home or work is already totally feasible from a standard grid connection. Many already do so. Small electric cars, such as a Nissan Leaf, require a usually existing standard 230 volt ac 15 amp power point and a power cable that plugs into the car’s on-board charge.
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 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...
Why the move to electric vehicles? It is largely because in the past few years there has become an increasing realisation that it is impossible to totally remove emissions from petrol engines. This applies even more so to diesel engines (although to their shame, major European car makers used fraudulent methods to cover this up). It is now all but certain that diesel cars and diesel 4WDs will cease being made after 2030. Many makers are planning an earlier date for diesel as it is becoming clear that it virtually impossible to remove the major polluting components.
ISolar usage in the USA is rapidly becoming cheaper and growing increasingly faster.
In 2004, the average price of an installed 10 kilowatt rooftop solar module was about US$3.50 per watt. As of early 2021 an installed 10 kilowatt system is likely to ranges from $17,750 to $24,000 ($1.77 -$2.40 per watt).
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.
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 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!
Inverters for homes and properties convert the typical 24 or 48 volt battery bank’s output into grid-like 110 or 230 volt alternating current. Consider only those marketed as sine-wave (not modified sine wave etc). High quality sine wave inverters produce electricity that is ‘cleaner’ than the average grid supply. Other types do not. Their output is likely to wreck sensitive electronics.
Grid connect solar problems include, false promotion and vendor claims, incompetent installation etc. Here’s what vendors may not tell you.
Solar shadowing is like blocking a water pipe. If one cell is fully shadowed, it does not just block current through that cell, it blocks the entire string. Because of this, only a few shadowed cells can block your total solar output. If partially shadowed, (e.g. by light cloud) the loss is proportional to the amount of sunlight being blocked. The higher quality solar modules produce some output unless clouding is severe. It is, however, rare to have zero during ‘daylight hours’.
Top quality solar modules for homes and properties catch 18% to 20% of the solar energy available. This is typically 140 watts-180 watts per square metre in full sun from about 10 am to 2 pm. Input tapes off before and after. The most efficient are priced accordingly.
Updated 2020 How much solar capacity do I need This article answers how much solar capacity do I need. It's valid anywhere in the world that has enough sun. It can save you a lot of money. The map below shows the amount you typically have available in Australia....
A backup generator is close to essential for home and property stand-alone solar. You can choose to down without but doing so may triple the cost of that system.
We self-built our all solar house in Australia’s far north. It is beautiful and practicable. Living with solar alone is 100% possible. Here’s how and why.
Solar is now so cheap that the main limitation is the space available for the solar modules. It is not possible to have too much solar. Ample solar prolongs battery life. It also and ensures at least some output during overcast days. There is no risk of overcharging, nor overloading the associated solar regulator. That regulator blocks the excess current.
Some solar scams are widespread while others are rare. It’s vital to keep yourself informed. Here are 10 scams. There are more to come.
