All you need to know about solar water heaters

Do you need lots of hot water? Are your utility bills increasing because of it? If yes, there is a cost-effective option to producing hot water in solar water heaters.

Solar water heaters have been around for many years, where it harnesses sunlight to heat water. They may seem more expensive than other water heaters at first. However, the money you save in the long run makes it worth the Missouri solar power investment.

Solar water heater parts

The most important solar water parts comprise of one or more collectors necessary for trapping the sun’s energy and storage tank that’s well insulated.

Collectors

The three collector types are:

  1. Flat-plate collector panels with a dark plate and pipes placed behind a transparent glass or polymer cover. They are dark to help absorb heat better while sunlight passes through the transparent cover and heats the water.
  1. Integral collector systems comprise of a few black tubes placed in an insulated box. The box in turn has a transparent glass or plastic cover. The tubes absorb heat to heat water. It then enters a traditional storage water heater and may work with an instant water heater.
  1. Evacuated tube collectors comprise of parallel placed transparent tubes with inner metal absorber tubes for absorbing the sun’s heat. They are most common in commercial Missouri solar applications.

The storage tank

The storage tanks here are generally large capacity traditional electric or gas water heaters. If you wonder why the large capacity, well it’s to provide for more heated water during overcast weathers.

The conventional heater’s heating elements act as a back-up resource to help compensate when the solar collectors can’t provide sufficient hot water. Single-tank systems use the system for back-up and storage water.  Two-tank systems pre-heat water before it is stored in the main water tank.

Cost determining factors

There are various factors that determine a solar water heater’s cost effectiveness like:

· Usage

The solar water heater repays itself with time, especially if you use more hot water. In short, they save the most money in large families or places with high hot water consumption.

· Cost

Passive systems may seem a cheaper option, but they are not always practical to use.

· Available sunlight

Missouri solar applications function exceptionally well in places with lots of sunlight. Choose the location to set up the system wisely. It’s because collectors work the best if and when exposed to direct sunlight for longer periods.  

· Other incentives

There are tax credits and other similar incentives which will help reduce your initial investment amount, and give you a shorter payback time.  

Make sure you find out all about your local solar power incentives before finally deciding on your solar water heater.  It’s a combination of these factors that reduce the solar water heating system’s initial costs to reduce the payback time.

Solar water heater types

There are two solar water heater types- active and passive.  Active variants use a pump to circulate water between the collectors and storage tank. The passive variants rely only on natural convention for circulating water.

1. Active water heaters

These solar water heaters run on two circulation types.  

  • Direct circulation heaters circulate water from the collectors to the storage tank. They are better for places where the temperatures seldom under zero.
  • Indirect circulation systems are better for cold climates where pipes may end up frozen. They prevent possible pipe freezing by circulating non-freezing heat transfer fluid through the pipes and storage tank.

2. Passive water heaters

These are cheaper but less efficient and run by integral collector/storage or thermosyphon systems.

  • The integral collector/storage system preheats water in a traditional water heater. They are best used in climates where temperatures don’t go under zero too often.
  • The thermosyphon systems circulate water through natural convection. The tank is placed at a spot that’[s higher than where the collector panels are. The hot water in the panels can thus flow upwards into the storage tank. The cool water in the tank then returns to the collector system for heating.

Installation and maintenance

It’s important that you have a qualified and experienced contractor install your system. Do check their license, the BBB for complaints and speak to their past customers before selecting the right person.

It’s not enough if the contractor just installs your water heater. They should also keep a regular maintenance schedule.

Simple passive systems with minimal parts need less maintenance. However do discuss, and decide on the best maintenance requirements of an active system with the installer.

Now that you know all about solar water heating systems, you can buy yours from one of the solar companies in Missouri.

The eight pros and four cons of Solar Photovoltaic Cells

THE EIGHT PROS AND FOUR CONS
 OF SOLAR PHOTOVOLTAIC CELLS

Solar photovoltaic cells- reading the phrase makes most people wonder if it’s the same as solar panels. Well, you aren’t wrong because both are closely connected parts of your solar PV system.

However, there is a slight difference in the phrases.

Solar panels are panels that convert sunlight into another form of energy, typically heat or electricity. The panels convert sunlight into electricity with the help of solar photovoltaic cells.

All the PV cells in a single solar panel can generate sufficient electricity to power your home.

PROS AND CONS OF SOLAR PV CELLS

With the sun radiating enough solar energy to provide for a year’s human consumption, it’s indeed wise to invest solar PV panels! However, everything in life has its share of advantages and disadvantages, including PV cells.

Yes, the very PV cell which is environmentally friendly, and helps you save in utility costs, has some ups and downs. Reading the following list of pros and cons enables you to understand Missouri solar power better before investing.

SOLAR PV ADVANTAGES

1. A CLEAN AND GREEN ENERGY SOURCE

The most prominent advantage of PV cells is the clean and green energy it provides. There is no fear or worry about the panels generating any harmful greenhouse gases into the air like carbon dioxide.

2. FREE RAW MATERIALS

The second advantage is that you don’t have to pay for raw materials! PV cells depend on solar energy to produce electricity, which is freely available in abundance around you.

It’s a win-win solution for you.

While you will have to make an initial investment in the system, solar power is natural, free, and available in abundance for a long time. You end up saving in electricity costs once you start using the energy generated by PV cells.

3. VERSATILITY

Solar PV cells can generate electricity anywhere. All it requires is sunlight, making it a useful energy source while going on camping trips, traveling, and on long car trips.

4. SIGNIFICANT IMPACT ON SMART ENERGY NETWORKS

Solar PV has an integral role in smart energy networks, which work on distributed power generation (DPG). DPGs are exceptionally environmentally friendly because it helps reduce the production of electricity at centralized power plants.

Besides, DPGs reduce the environmental impacts of a centralized generation system. It depends on, and uses the sun’s energy that otherwise ends up wasted, to generate electricity.

Lastly, DPG also helps reduce any possible loss of energy during the transmission and distribution of electricity in the power system.

5. REDUCED COSTS

About costs, while solar panels Columbia mo were indeed once expensive, its rates are expected to reduce substantially within the next few years. So considering its economic viability and environmental sustainability, PV cells are indeed an investment worth making.

Besides, solar PV cell systems are also a renewable energy system promoted through government subsidy funding. The financial incentives offered makes solar energy panels an attractive investment alternative.

6. LOW IN MAINTENANCE

Solar PV cells are known for their low maintenance and operating costs compared with other renewable energy systems.

7. SILENT

Solar PV is perfect for urban areas and residential applications because it doesn’t produce any noise.

8. EASY TO INSTALL

Last but not least, you can easily install residential solar panels on rooftops or just on the ground without interfering with your lifestyle.

DISADVANTAGES OF SOLAR PV CELLS

1. INTERMITTENCY ISSUES

Like all other renewable energy sources, solar energy and PV cells have intermittency problems. It means it’s not continuously available for converting into electricity like during night-time and during cloudy or rainy weather. So PV cells will probably be incapable of meeting an electric power system’s demand.

2. LESS RELIABLE POWER OPTION

It’s this intermittency and unpredictability that makes solar energy panels a less reliable power solution.

3. ADDITIONAL INVESTMENTS

PV cells require an additional investment in inverters and storage batteries. Inverters convert direct electricity to alternating electricity to use on your power network.

Storage batteries prove helpful in providing a continuous power of electric power in on-grid connections. This additional investment can, however, provide a solution for the PV cells’ intermittency issues.

4. USES A LARGE AREA

The large areas of land used for land-mounted PV panel installations remain committed to the purpose. That’s why it’s vital that you wisely select a spot for the solar energy system, and why many people install it upon their roofs.

5. EASILY DAMAGED

While solar PV needs no maintenance or operating costs, its fragility means it’s easily damaged. There’s a solution here in the form of additional insurance coverage to safeguard your investment.

Now that you know all about solar PV cells, it’s time to turn to one of the solar companies in Missouri for more information.

There’s no point in even considering getting a commercial PV system if you don’t have clearly defined company goals. You need to know why you are investing in the PV system.

You also have to know what you plan to achieve, like cutting costs and setting your social responsibility message. It helps solar providers tailor their bid response as per your needs, and show how they can help meet your goals.

3. Create your request for proposal (RFP):

It’s when you know your goals and the concept that you can come up with the request for proposal. The RFP intimidates solar providers that your company is ready to receive bids for solar projects. It lets your company outline the bidding process, contract terms, and project specifications to prospective solar providers.

4. You can also have a Request for Qualification (RFQ)

You can even issue a Request for Qualification (RFQ) before sending the RFP. It can have the same weighing process used for identifying a few qualified bidders.

It helps save your time because it shortlists the top bidders. You can then send the RFP to these selected few providers.

5. Create your selection criteria.

It helps to develop a scoring system in the RFP to help you select the right provider. Create the system based on the input from different segments of your organization like procurement, finance, engineering, and sustainability officers.

You are sure to come up with tons of suggestions from them. You, however, will have to come up with the final list based on the following characteristics:

  • Cost-effectiveness-If the provider’s bid matches or excels competitor bids in meeting your company’s financial savings target.
  • System design and technical aspects-If the provider’s customized system design meets or excels with your RFP specifications.
