THE STRUCTURE OF YOUR ROOF
Your roof needs to have enough room for your solar panels and be strong enough to support them.
TE HANGANGA O TŌ TUANUI
Me rahi nei tō tuanui, me kaha nōki kia tika ai te whakaū i ngā papa pūngao kōmaru.
THE DIRECTION OF YOUR ROOF
Roofs facing north, northwest or northeast will get most sunlight throughout the day, but your roof would still be suitable for solar panels if it faces east or west.
TE AHU O TŌ TUANUI
Ko ngā tuanui e ahu atu ana ki te raki, ki te uru-mā-raki, ki te marangai mā-raro rānei hei ā whiti nui nei e te rā, erangi e pai tonu ana pēnā ka ahu atu anō ki te marangai, ki te uru rānei.
HOUSEHOLD ENERGY CONSUMPTION
To make the most of solar energy, it is best to do things that require high amounts of power during the day: heating water, spas and pools, running air conditioning systems, doing laundry, taking showers. For flexibility you may need to consider battery storage.
KO TE WHAKAPETO PŪNGAO Ā-WHARE
E whai hua ai te pūngao kōmaru, mahia ngā meae kaha kai hiko ana i te rā, arā, ko te whakawera wai, ngā puna kaukau, ngā whāhauhau, te horoi kākahu, te uwhiuwhi anō hoki. Kia ngāwari ake nei me whakaaro kau ki ngā pūhiko.
COST VERSUS BENEFIT
Solar panels and installation typically costs between $10,000-$15,000 for an average household. You still need to draw power from the grid when it’s not sunny. Make sure to check that your outlay pays for itself over time.
Alternatively, you could consider a low or no-cost installation paired with a 25-year contract with a solar provider.
HE UTU, HE HUA RĀNEI
Ko te utu kia whakaū i ngā papa pūngao kōmaru kei te takiwā o te $10,000 ki te $15,000 puano mō tētahi whare. Me whakamahi tonu koe i te hiko nō ngā taura hiko ā ngā rangi kāpuapua. Me āta tirotiro i te hanga o te utu, e ea ai te whakaū, ā haere nei te wā.
Waihoki, hei whakaaro atu anō ki tētahi kirimana utu kore, utu iti rānei e 25 tau te roa māu, nā tētahi kamupene pūngao kōmaru.
BATTERY STORAGE
This is a great solution if you want power available during outages, or to use power during peak times when it’s most expensive. Expect to pay between $10,000 - $15,000 for a battery in addition to your solar installation.
Consult an expert to make sure your battery provides electricity when you need it to. If you sign a contract, make sure you understand the details – for example, you may not have control over when you use the battery.
TE PŪROKIROKI PŪHIKO
He whiringa pai tēnei ki te hiahia hiko koe ā ngā kotinga hiko, kia whakamahi rānei i te hiko i ngā taima matua e nui ana te utu. Me rite kia utu i te $10,000 ki te $15,000 puano hei hoko i tētahi pūhiko atu anō, koni atu i te whakaū pūngao kōmaru.
Me kōrero atu ki ngā mātanga kia tika ai te pūhiko mō ō hiahia katoa. Ki te haina tētahi kirimana me matua mārama ki ngā taipitopito kōrero - hei tauira, tērā pea kāhore i a koe te mana whakatau ko āhea mahia ai te pūhiko.
EXPORTING SOLAR ENERGY BACK TO THE GRID TO MAKE MONEY
Rooftop solar may not be the money maker you hope it is. You always pay more to use power from the grid than you make from exporting solar back in. If your goal is to make money, you need to shop around for the best deal.
KO TE TUKU I TE PŪNGAO KŌMARU KI TE KĀWEI HIKO HEI MONI MĀU
Ehara i te mea ko te pūngao kōmaru te puna moni e tumanakohia ana. Ka nui atu te utu kia whakamahia te hiko nō te kāwei hiko ki tērā i te moni e hua ai i te tuku atu. Mehemea e hiahia ana koe kia whai moni, me āta tirotiro kia rapua te mea pai atu ki a koe.
