Technology is moving quickly and domestic battery storage is becoming prominent.
Nearly 1 million UK homes have turned to solar energy, but there’s always been one tricky issue. The average household with solar panels simply cannot use all of the energy it produces at the time of production. During the day, when solar energy production is at its peak, excess energy is fed back to the National Grid, leaving homeowners paying for their electricity once the sun goes down.
The solution is a domestic battery storage system, which stores the excess energy until you’re ready to use it which can be later in the night.
Reliance on the grid and carbon footprint is reduced and it puts you another step forward towards self-sustainability with clean, renewable energy.
Types of Battery Storage
Household battery storage systems generally use one of two battery types, both with their advantages and disadvantages.
Lithium-ion: Commonly found in mobile phones, lithium-ion batteries are perfect for use in conjunction with an existing solar PV system. They are extremely efficient, and can discharge more stored energy than other types.
Lead acid: More like your car battery, these are great for off-grid properties, as they have increase storage power. They are significantly larger, heavier, and have a shorter lifespan, but they are also cheaper than lithium-ion battery storage devices.
Battery Storage Manufacturers
Domestic battery storage technology is constantly evolving, and there are a number of major players currently in the market including:
Tesla: Famed for its innovation in electric cars, Tesla’s huge-capacity 14kWh Powerwall 2 is a stylish wall-mounted modular battery storage device that is widely regarded as the current market-leader.
Powervault: This UK-based company offers a range of systems from 2-6kWh in either lead acid or Lithium-ion battery options. The unit itself is around the size of a dishwasher and is designed to fit alongside your integrated appliances.
LG Chem: The LG Chem is a compact home battery storage unit, which can be purchased in capacities from 3.3-6.5kWh. It’s also the same battery that is supplied with IKEA’s range of domestic solar energy products, which can be bought as a standalone device or in conjunction with solar panels.
Costs and Savings
The cost of buying and installing a household battery storage system varies according to the needs of each home. Economical options like the Powervault can start from £2500, and can rise to as much as £8,000 for a fully installed Tesla Powerwall. For the average home, a cost of between £4-5000 can be estimated, though it’s hoped this can eventually be recouped over the years in energy bill savings.
Powervault claim savings of up to 20% on your current electricity bill. In addition to this, for those on a variable time-of-day tariff such as Economy 7, extra savings of up to 15% can be made by storing cheaper off-peak energy for use in peak times.
The result could be lower fuel bills, lower carbon emissions and the knowledge you can power your home with clean, green, renewable energy.

Teknolojia inazidi kusonga haraka na kuhifadhi betri za nyumbani kunakuwa jambo la kawaida. Karibu nyumba milioni moja nchini Uingereza zimegeukia nishati ya jua, lakini daima kumekuwa na suala moja gumu. Nyumba ya kawaida yenye paneli za jua haiwezi kutumia nishati yote inayotokezwa wakati wa uzalishaji. Wakati wa mchana, wakati uzalishaji wa nishati ya jua ni juu yake, ziada ya nishati ni kulishwa nyuma kwa Gridi ya Taifa, kuacha wamiliki wa nyumba kulipa kwa ajili ya umeme wao mara jua inakwenda chini. Suluhisho ni mfumo wa kuhifadhi betri ya nyumbani, ambayo huhifadhi nishati ya ziada mpaka uwe tayari kuitumia ambayo inaweza kuwa baadaye usiku. Kutegemea gridi na alama ya kaboni hupunguzwa na inakuweka hatua nyingine mbele kuelekea kujitunza na nishati safi, mbadala. Aina ya Battery Storage: Mifumo ya kuhifadhi betri ya nyumbani kwa ujumla hutumia moja ya aina mbili za betri, zote mbili na faida na hasara zao. Lithium-ion: Kwa kawaida hupatikana katika simu za mkononi, betri za lithiamu-ion ni kamili kwa matumizi pamoja na mfumo wa sasa wa jua wa PV. Wao ni ufanisi sana, na wanaweza kutolewa nishati zaidi kuhifadhiwa kuliko aina nyingine. Bomba la risasi: Bati ya gari ni bora kwa ajili ya mali ya nje ya gridi, kwani ina uwezo wa kuhifadhi. Ni kubwa zaidi, nzito zaidi, na zina maisha mafupi, lakini pia ni za bei nafuu kuliko vifaa vya kuhifadhi betri za lithiamu-ion. Tesla ina uwezo mkubwa wa 14kWh Powerwall 2 na ina uwezo wa kuhifadhi betri ya modular iliyowekwa ukutani. PowerVault ni kampuni ya Uingereza ya umeme ya umeme ambayo inatoa aina ya umeme kutoka kwa 2kWh hadi 6kWh kwa betri ya asidi ya risasi au betri ya lithiamu-ion. Kifaa hicho ni karibu na ukubwa wa mashine ya kuosha vyombo na ni iliyoundwa ili kufaa pamoja na vifaa vyako integrated. LG Chem ni kifaa cha kuhifadhi betri ya nyumbani, ambayo inaweza kununuliwa katika uwezo kutoka 3.3-6.5kWh. Pia ni betri hiyo hiyo ambayo hutolewa na IKEA ya mbalimbali ya bidhaa za nishati ya jua ya nyumbani, ambayo inaweza kununuliwa kama kifaa cha kujitegemea au pamoja na paneli za jua. Gharama ya kununua na kufunga mfumo wa kuhifadhi betri ya nyumbani hutofautiana kulingana na mahitaji ya kila nyumba. Kwa mfano, PowerVault inaweza kuwa na bei ya chini ya £ 2,500 na inaweza kuongezeka hadi £ 8,000 kwa Tesla Powerwall iliyowekwa kikamilifu. Kwa nyumba ya kawaida, gharama ya kati ya £ 4-5000 inaweza kukadiriwa, ingawa inatarajiwa hii inaweza hatimaye kurejeshwa kwa miaka katika akiba ya bili ya nishati. PowerVault inatoa upatikanaji wa gharama za umeme kwa watumiaji na inatoa upatikanaji wa gharama za umeme kwa watumiaji. Kwa wale walio na kiwango cha muda wa siku kama vile Uchumi 7, mapato ya ziada ya hadi 15% yanaweza kufanywa kwa kuhifadhi nishati ya chini ya wakati wa kilele kwa matumizi katika nyakati za kilele. Matokeo yake yanaweza kuwa bili za chini za mafuta, uzalishaji wa chini wa kaboni na maarifa ya jinsi ya kuendesha nyumba yako na nishati safi, ya kijani kibichi, na mbadala.
