Solar Electric Panel Buying Guide – Choose the Best
Solar panels or photovoltaic (PV) panels are in high demand now as it can generate the electrical power needed for your home or other energy needs. As the other conventional energy resources are drying out, people are turning to more natural and everlasting source of energy, the sun, to meet their increasing power consumption needs.
When you are getting on to purchase a solar electrical system, make sure that you check out all available packages which companies offer and the subsidies by the governments. In light of the loan programs, which the solar service providers offer and the tax benefits by the state, you may be able to get PV power at a far reduced price than actual.
The cost factor
Let’s see an example; a photovoltaic solar panel which can provide electricity for the entire home by meeting the fire and electric compliance requirements is eligible to get a tax rebate of up to 30%, say around $500 for a 0.5 kW solar power system. However, many of such programs are for the residences only, not for large-scale plants.
However, don’t jump into any kind of random programs while shopping for the photovoltaic cell system, but keep the following considerations in mind to get the best purchase.
- Power output
How much is that your home needs? If you can get a break down of your daily power usage from the electricity bill, it is easy to determine how much wattage you need to generate from your PV array to meet the needs. During the peak hours when sun delivers the best, the output may range anywhere from 40 watts to 200 watts from an ideal solar systems. The difference is based on the technology, size of the panel, and cells used etc.
- Cost per Wattage
Another effective way to calculate the cost of purchasing photovoltaic cells is to consider the dollars-per-watt cost ratio. A round estimate can be like, if you purchase the PV modules which are priced at $4 to $5 per wattage means that the system can deliver a maximum output of 100 Watts if you spend $400 to $500. Using this method, you can roughly calculate how much you need to shell out to lit up your home fully.
It is insolation (not insulation) which measures the total amount of sunshine directly falls on to each square meter of the solar panel per day. This is generally measured in kilowatts and will help determine how much energy you expect the PV array to produce daily.
Mounting the solar array
Even you buy the best, the tilt of the solar array also is important based on the geographical specifications of your area to ensure maximum efficiency. There are various types of solar array mounting systems for home purpose and picking the right one is critical to ensure the best ROI.
You may feel installing the PV modules simply flat on the roof to be aesthetically pleasing, but this may significantly reduce the power generation during the low-light hours or rainy days. Don’t doubt whether PV cells can work at rain, it can, but generates only lesser energy. Now, there are advanced mounting stands too which can automatically turn and adjust the tilt to track the sun across the sky.
Industrial Equipment – Pallet Jack
What makes this material handling equipment so popular
The only manually operated equipment that is capable of handling pallets is the pallet jack also known as pallet truck. You will hardly find any warehouse that does not have at least one piece of it. This basic material handling equipment is also seen at places like the airport and docks. Loaded pallets resting on the ground have to be slightly lifted and then pushed to be moved from one place to another. Pallet jacks move on wheels and are capable of lifting loaded pallets and also moving it. Lifting of load is achieved by using a small hydraulic unit that generates the power necessary to keep the pallet elevated till the time it has been moved. The equipment is cheap and highly efficient that contributes to its wide scale use in all areas of material handling.
Using the power of oil
The manual pallet truck is fitted with a small hydraulic unit that makes the equipment all powerful to handle heavy loads. The hydraulic unit if filled with hydraulic oil that is pumped manually to raise the pallet up to a certain height above the ground. Once the round clearance is ensured, the operator can push the truck in the direction where it has to be moved. The handle of the truck is used as lever to perform the pumping action. After the pallet has been moved, the jack is pulled back after the forks of the jack are lowered. By pressing a release valve the hydraulic pressure is released that results in lowering the forks.
Electrical pallet jacks
In order to increase efficiencies and capacities of handling loads, electrical pallet jacks are also used. The construction and functionalities of the powered jacks are similar to manual pallet jacks but the difference is in the driving mechanism. Human power that is required in manoeuvring manual pallet trucks is replaced by electrical power that is derived from batteries. These trucks can handle much heavier loads and the operator has to only press some switches to make the equipment work.
Reasons for popularity
Convenience and ease in handling materials has been the reason for popularity of pallet jacks. Economical operations that are also very efficient and enhance productivity are the other causes for using the equipment. Since the equipment is small in size (the longest fork length is 8 feet) and has a very small turning angle, it can be operated in small spaces that has also been a reason for choosing it. Considering the heavy loads that the small equipment can handle it is considered to be a powerhouse in material handling.
Pallet jacks are quite safe in handling materials. Although safety is built into the design and construction of the equipment, users have to be careful in not to cross the threshold levels of safety. Every equipment is designed for some maximum load that should never be exceeded. Movement of loaded equipments has to be slow and heavy loads should never be pulled.
Regular maintenance and proper upkeep of pallet jacks ensure its safety. You can find a lot of information about Electric Pallet Jack Online.
