Integrated Water Systems in Small Towns and Rural Communities

Sustainable Solutions with Solar Water Pumps

By 2030 the world will need to produce 50 percent more for food and energy and 30 percent more fresh water. Solar pumps are a reliable technology which can compete with conventional pump technologies such as diesel pumping. Large amounts of energy are used in the entire water cycle.

Water Pumps Play a Major Role in all Water and Waste Water Processes

Smart Water Technology remote monitoring and control of water pipes and plants help reduce water distribution losses, improve smart energy use for water management and reduce maintenance costs.

Solar Pumps do not require fuel, are positioned close to demand, hence no distribution losses, require little maintenance, are air pollution free and do not require batteries as energy is stored in high level storage tank.

Rural Water Supplies hand-pumps are an efficient way to supply small communities up to 300 people; motorized pumps are needed to supply larger communities with water requirements above 24 m3/hour.

Solar Pumps Operate in Deep Wells Rivers and Lakes Water is Stored in Tanks or Injected Pipes

Comparing Diesel and Solar PV systems have higher initial costs whereas diesel pumps are very uneconomical at low flow rates; PV pumps are more economical even at higher pumping heads and larger volumes - > 8000 m3/day. With a 20% diesel price increase, the range increases to over 100kWp pumping power. PV module costs have decreased in the last several years.

ESCo is an energy and water service/savings company that provides design, implementation and financing of energy/water saving projects, retrofitting, conservation, infrastructure outsourcing, power generation and supply, as well as risk management.

Solar Inverters Pump Applications inverters provide continuous water pumping during the day and feature maximum energy efficiency and top water flow rate in all solar conditions. A manual switch can be connected to an AC three-phase supply with a backup diesel pump for night service, as required.

With 140GW Installed World-wide Pumped Storage Hydro Accounts for 99% of World’s Storage

Local Development solar water pumps can succeed in small towns and rural communities that have access to local system integrators and manufacturers, technical training capabilities, software tools for proper dimensioning and simulations, complete PV modules, inverters and pump kits as well as local companies partnerships for system assembly, after sales support, spare parts availability and web based remote monitoring and assistance.
