New location for the solar panels

The solar water pumping project in Paang Bundok was installed in 2005 providing water supply to 85 families in Paang Bundok.  Unfortunately, during the three-year operation of the potable water system, some of its main technical parts (electrical inverter) were accidentally hit twice by lightning that affected the over-all performance. Most of the solar panels were badly damaged and some inverters were missing.  Although some parts replacement was done with the help of a partner institution, the maximum capacity of the water system to supply the requirement of the whole community was greatly affected.  After this episode, the decision to move the solar panels system closer to the community was taken and also install transition line from the source to the new system location, around 500 meters far, buy a new inverter and repair the solar panels in order to rehabilitate the system.

At present, the whole potable water system is at zero performance level due to the missing inverters and damaged solar panels.  From September 2008 up to this time, the residents are doing the old ways of fetching water for their daily needs.

Thanks to you and Global Giving that facilitated online fundraising, SIBAT engineers are now working on the rehabilitation of the solar water pumping system.

Project Update:

Presently, the solar panels have already been repaired and placed in the new location closer to the community.  The inverter has been delivered to the community and already in place.  The transmission line from the water source to the location of the new solar panels have been installed.  The project team is composed of Carlo Fabia (electrical engineer), Diana Benato (mechanical engineer), Jade Angngalao (agricultural engineer and Myrna Herisano (community facilitator).

During the site visit to rehabilitate the the system, SIBAT Team has discovered that the pump is not functional any more probably due to the fact that it has been left inoperative for a long period.  The team has decided to bring the pump to the SIBAT workshop in Urdaneta, Pangasinan so as to clean and make it work again before take the decision to buy a new pump.  Installation of the pump is targeted to be completed within the month of December 2011. 

The project engineers, Carlo Fabia and Diana Benato, will then test the repaired pump and plan out next activities for making the water pumping system fully operational.  As such, after testing, if the pump is working, the next activities will be for the assessing/testing and conduct of necessary repairs of the water distribution line from the water supply to the households.  If in the case that the repaired pump will not work, then SIBAT will then have to procure a new pump for the system.

8-9 October 2011:  Installation of the inverter.  The team went to Paang Bundok to clean-up and do maintenance work of the solar system, install the new inverter and the transmission line from the water source to the solar panels located 500m from Paliparan Spring which is the water source.  Unfortunately, the engineers were unable to test the pump as it was rainy weather and there was not enough power to run the pump.

26-27 October 2011:  Test of the pump.  The team returned to the site to test the pump on a sunny weekend, and discovered that the pump was not functional due to impurity inside the rotor as the pump has been left without working for a long period.  As such, the engineers brought the pump for clean-up and repair work to SIBAT’s workshop in Urdaneta.  

11-17 November 2011:  Pump Repair in Machine Shop in Urdaneta, Pangasinan.  The pump was cleaned as it has already some parts with rust, pump oil was replaced and now ready for testing.

Next site visit on December 2011:  Pump Testing.  The next site visit will entail testing of the repaired pump, and once functional, the team will now proceed to testing and repair of the water distribution lines from the water source to the households.  If the repaired pump is not working, then there will be a need to procure a new pump for the system.

Thank you for supporting the rehabilitation of the solar water pumping project in Paang Bundok.  SIBAT engineers were able to repair the damaged solar panels and have now installed it in Paang Bundok.  The technical work is now halfway through, made possible with your support that provided for the technical repairs and installation expenses of the project.  As soon as possible, the water pump will also then be repaired that will then bring up the water directly from the spring to the storage tank for distribution to the 85 families in the village.

The next phase will be restoration of the water distribution system including the water pump equipment.  SIBAT engineers – Carlo Fabia and Diana Benato have already designed the appropriate water system layout that will optimize the water distribution system.

Paang Bundok Solar Water Pump Project Rehabilitation

Last January 19-25, 2011 a technical team composed of SIBAT’s Renewable Energy Technical Manager Chris Alfonso, Electrical Engineer Francis Lacuesta, Agricultural Engineer Jade Angngalao and Community Organizer Myrna Herisano conducted a project site visit to prepare for the technical rehabilitation of the Paang Bundok Solar Water Pumping System. 

The visit included a technical survey and monitoring to finalize the design of the major technical components of the project.  The findings and technical recommendations which were shared to the community were the following: 

There is  a need to install a bigger tank in the highest portion of the area for sufficient water distribution to all households;

  1. Bigger size of cable required in order to minimize the voltage drop due to the distance and also because the pump is a low voltage system; and
  2. Need to install appropriate (bigger) size pipe to the pump outlet;
  3. Set up parallel pipe distribution; and
  4. Need to raise additional project funds.

The project team also took the opportunity to consult and discuss with the Paang Bundok villagers regarding the rehabilitation requirements, local manpower and responsibilities of the PO that will be required for the rehabilitation work and the available funds raised from UP-ERG and through Global Giving.  

Initial Rehabilitation Activities during April – May, 2011.

The initial funds available (raised through Global Giving and UP-ERG) were then used to canvass and procure project materials – cement, pipes and electrical materials, and preparatory activities such as inventory of existing materials, checking and fixing all pipelines previously installed.  SIBAT engineers have been working on finalizing an appropriate technical design and workplan together with the villagers towards ensuring proper fit and implementation whilst raising more funds necessary for project completion.

Technical Design and Workplan for the Rehabilitation of the Paang Bundok Solar Powered Water Pumping Station in San Celestino, Lipa, Batangas

March 1, 2011

Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP).  Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam.  Photovoltaics converts light into electric current using the photoelectric effect.

The solar panels convert sunlight into electrical power. Stronger sunlight will generate more power.  The longer the sun shines on the panels the more energy will be generated.  Clouds will reduce the power output of the panels. The solar panels work automatically and only need minimal maintenance.

Solar energy is not available at night, making energy storage an important issue in order to provide the continuous availability of energy.  Solar power is an intermittent source, meaning that all available output must be taken when it is available and either stored for when it can be used, or transported, over transmission lines, to where it can be used. 

Estimated Project Cost & Comparison for a Three Phase & Single Phase System: 

The estimated cost comparison for the 3-phase is in the amount of PhP157,480 while for a single-phase system cost estimate is pegged at PhP261,610 which will cover costs for hardware and materials.  Labor cost and some locally available materials will be provided as local counterpart of Paang Bundok villagers.  The local government units are also being approached for additional financial and technical support.  Final electrical system design will then be based on available funds and resources that will also consider system reliability, affordability, application and resiliency to climate change. 

Estimated Duration and Work Plan:

The estimated duration for rehabilitating the Paang Bundok solar water pumping project will cover a period of one month, as soon as project funds are fully secured. 


Solar frame & transmission post assembly:  1st- 2nd week

Electrical Wiring  Installation:  3rd week

Testing and Commissioning of PV solar water pumping station:  4th week

Current Efforts in Fundraising for Paang Bundok’s Proposed Solar Wind Hybrid for Household Water Distribution and Livestock Raising

Project Location:  Sitio Paang Bundok, San Celestino, Lipa, Batangas, Philippines

Samahang Patubig ng Paang Bundok (SPPB) and Sibol ng Agham at Teknolohiya (SIBAT) has been mobilizing the Batangas local government unit (barangay, municipal, provincial and congressman) to provide financial, material and support services to the proposed rehabilitation and upgrading of the Paang Bundok’s solar-wind water pumping project.

The following LGUs were approached and have given their initial commitment for project support in kind, material and financial support.

  1. Honorable Congressman Mark Llandro Mendoza
  2. Honorable Vilma Santos Recto, Provincial Governor
  3. Lipa Mayor  Meynardo Sabili
  4. Hon. Romel Malaluan, Punong Barangay, San Celestino, Lipa

Project Brief:

The main project objective is to rehabilitate and upgrade the defunct solar water pumping system in Brgy. San Celestino of Lipa in Batangas, Philippines for 85 rural poor Filipino families (total population – 435) with clean drinking and household water needs (i.e., bathing, washing and cleaning).  Previously installed in 2005 by SIBAT, it was destroyed by lightning in September 2008 rendering it non-functional up to now.  SIBAT engineers will rehabilitate the solar water pumping project - replacement of solar panels, charge controllers, batteries, electrical inverters and rewiring of cables including necessary civil works.  The villagers will provide labor counterpart.

The project will provide Paang Bundok with at least 17 m3 of water daily for their household consumption.  It will ensure steady water supply direct to their houses, thereby ensuring accessibility, sanitary conditions, and minimize if not totally eliminate recurring water borne diseases in the community.  The villagers will then have more time for other productive and learning activities, as the drudgery and the time spent in manual fetching of water will be done away with.

During the rainy season (May-December), the project can provide more water hence increasing the volume of water being supplied that can then supply nearby sitios.

Through the solar water pumping project, 435 poor Filipinos will be provided clean drinking water hence reducing chronic waterborne diseases, especially children.  Backyard gardening and livestock raising will also be possible, hence will provide additional nutritional vegetables and open up income generating opportunities at the household level. 

Currently, SIBAT project team is preparing for a more detailed feasibility study to improve the technical design and the power enterprise component of the project.  Local produce such as coffee processing from dehulling, dehusking, shelling, drying, roasting up to product packaging may be integrated so as to provide value to their coffee production.  Black pepper can also be looked into for integration and product development.  The enterprise livelihood component will further enhance and strengthen the project’s sustainability and economic viability, ultimately benefiting the villagers and organizational strengthening of the Samahang Patubig ng Paang Bundok (SPPB).
